In various embodiments, the validator selection engine 106 can be configured to select a validator to apply to at least one data set for use in validating data in the data set. A validator can include at least one validation parameter and a validation routine for use in validating data. A validation parameter, included as part of a validator, can be used to select statistics to extract from data in a data set for purposes of validating the data. For example, a validation parameter can indicate a specific column in a table to extract statistics from for purposes of validating the data. In another example, a validation parameter can identify specific columns that include unique identifiers of rows in a table. A validation parameter, included as part of a validator, can be pre-defined or set by a user. For example, a user can indicate through user input specific columns to generate statistics from for purposes of determining if the data is valid. A validation routine, included as part of a validator, can include rules or functions performed on statistics extracted from data to determine if the data is valid. For example, a validation routine can specify determining a maximum value, a mean value, and a minimum value for all values in a column in a table, and compare the values to threshold values.
In various embodiments, the validator selection engine 106 can be configured to present a plurality of pre-defined validators to a user. A user can select one or a plurality of pre-defined validators presented to them for purposes of applying the validators to a data set to validate data in the data set. Examples of pre-defined validators include but are not limited to: a numeric summary validator which can include a validation parameter of an identification of a specific numeric type column in a table and a validation routine of determining one or a combination of a mean value, a maximum value, and a minimum value for values in the column; a key statistics validator which can include validation parameters of an identification of one or a plurality of specific columns in a table and one or a combination of validation routines of calculating row counts for the columns, counts of distinct values in the columns, whether the one or a plurality of specific columns can act as a primary key, and determine a text match regular expression pattern; a null percentage validator which can include a validation parameter of an identification of a specific column in a table and one or a combination of validation routines of determining how many rows have null values in the column and a percent of rows in the column having null values; a column relation validator which can include validation parameters of an identification of one or a plurality of specific columns in a table and one or a combination of validation routines of determining the relation between values in the columns, e.g. one-to-one, one-to-many, many-to-one, and many-to-many; a join statistics validator which can include one or a plurality of validation parameters of join keys between tables and one or a combination of validation routines of determining how many rows join between the tables and how many rows fail to join between the tables; a column histogram validator which can include validation parameters of an identification of a column, a histogram, and how many elements in the column to keep and a validation routine of determining an occurrence rate of a elements above, at, or below a threshold frequency occurrence rate; and a table equality validator which can include validation parameters of an identification of two specific tables and one or a combination of validation routines of determining if the two tables have the same schema, if the two tables have the same row count, and the exact equality between the two tables.
In various embodiments, the validator selection engine 106 can be configured to generate a customized validator for a user based on user input. The validator selection engine 106 can generate a customized validator by creating a validator with either or both customized validation routines and validation parameters. For example, if a user wants to compute specific statistics for purposes of validating data, then the validator selection engine 106 can generate a custom validator with validation parameters for use in generating the specific statistics when the custom validator is applied to a data set. In another example, if a user wants to make sure specific statistics meet specific criteria in validating data of a data set, then the validator section engine 106 can generate one or a combination of validation routines to test whether the specific statistics meet the specific criteria as part of validating the data of the data set. The validator selection engine 106 can generate a customized validator by modifying either or both validation parameters and validation routines of a pre-defined validator. For example, the validator selection engine 106 can modify a numeric summary validator to create a customized validator by modifying a validation routine of the numeric summary validator to include summing the maximum and minimum values in a column.
In various embodiments, the validator application engine 108 can be configured to apply one or a plurality of validators to one or a plurality of data sets for purposes of validating data in the one or plurality of data sets. In applying a validator to a data set, the validator application engine 108 can generate statistics from data in the data set using validation parameters included as part of the validator. For example, the validator application engine 108 can extract values of a specific column in a table based on an identification of the specific column as a validation parameter. Additionally, in applying a validator to a data set, the validator application engine 108 can determine if generated statistics through application of the validator are valid based on one or a plurality of validation routines included as part of the validator. For example, if a number of null values in a column of a table of a data set fails to reach a threshold null value amount, then the validator application engine can determine data of the data set is invalid.
In various embodiments, the validator application engine 108 can be configured to apply a validator to data in a data set based on one or a combination of receipt of instructions from a user, a passage of a specific amount of time, and an occurrence of a change to data in a data set. For example, the validator application engine 108 can apply a validator to data in a data bet upon receipt of re-application instructions from a user. In another example, the validator application engine 108 can apply a validator to data in a data set after twenty-four hours have passed since a validator was last applied to the data for purposes of validating the data. In yet another example, the validator application engine 108 can apply a validator to data in a data set after values have been added to a column of a table of the data set. In various embodiments, the validator application engine 108 can apply or re-apply a validator to data in a data after a specific amount of time set by a user. For example, a user can specify applying a validator to data in a data set every twelve hours.

For example, a data quality report generated by the data quality determination engine 110 can indicate one or combination of an identification of specific data that was tested for purposes of validity, whether or not data is found to be valid, an identification of a specific validator applied to data to determine if the data is valid, validation parameters of a validator applied to data to determine if the data is valid, statistics generated based on validation parameters and generated through application of a validator, validation routines of the validator used to determine if data is valid, times at which a validator was applied to data to determine validity, and triggers for applying a data validator to data to determine if the data is valid. Further a data quality report generated by the data quality determination engine 110 can include applicable data related to reporting of validity of data as it evolves over time, e.g. according to multiple instances of application of validators to validate data. For example, a data quality report generated by the data quality determination engine 110 can include prior values of statistics as part of validated data as it changes over time.
In various embodiments, the data quality determination engine 110 can be configured to generate a data quality report based on a determination of whether data in a data set is determined to be valid or invalid. The data quality determination engine 110 can generate a data quality report based on a determination of whether one or more statistics generated through application of a validator to a data set are determined to be invalid based on at least one validation routine associated with the validator. For example, the data quality determination engine 110 can generate a data quality report indicating specific statistics generated through application of a validator were found to be invalid based on a validation routine associated with the validator.
In various embodiments, the data quality determination engine 110 can flag a data set as invalid or valid. The data quality determination engine 110 can flag a data set as invalid or valid based on whether statistics generated through application of a validator to data of the data set are found invalid or valid according to at least one validation routine of the validator. For example, the data quality determination engine 110 can flag a data set as invalid if a number of statistics greater than a threshold number of statistics are found to be invalid according to a validation routine of a validator applied to data of the data set. The data quality determination engine 110 can use whether a data set is flagged as invalid or valid to generate a data quality report. For example, if a data set is flagged as invalid, then the data quality determination engine 110 can generate a data quality report to indicate the data set is invalid and the reasons the data set was found invalid, e.g. an identification of which specific statistics were found invalid.
In various embodiments, the data quality determination engine 110 can generate a new data quality report or update a data quality report after each instance of application of a validator to a data set. For example, each time a validator is applied to a data set to validate data in the data set, the data quality determination engine 110 can generate a new data quality report to reflect results of application of the validator to the data set in each instance of application of the validator. In another example, each time a validator is applied to a data set to validate data in the data set, the data quality determination engine 110 can update an already existing data quality report to include the results of application of the validator to the data set in each instance of application of the validator.
In various embodiments, the data quality determination engine 110 can provide a data quality report to a user through an applicable mechanism.

For example, if user preferences indicate a user wants to view a data quality report after is uploaded through a graphical user interface and have a notification sent informing them that the data quality report is available, then the data quality report transmission engine 408 can upload the data quality report and send a notification to the user informing them that the data quality report is available for review.
At block 502, a data set including data to validate is selected based on user input received from a user. For example, user input can indicate a table with data to validate. In certain embodiments, a user a plurality of data sets to validate can be selected based on user input received from a user. User input indicating a data set including data to validate can be generated and received based on user interactions with a graphical user interface, such as the graphical user interfaces described herein. An applicable system for controlling validation of data using a validator, such as the data validation systems described herein, can select a data set including data to validate based on user input received from a user.
At block 504, a validator to user in validating the data is selected based on user input. In selecting a validator to user, a list of pre-defined validators can be presented to the user, and the user can select a validator from the list of pre-defined validators, as indicated by the user input. Additionally, in selecting a validator, the validator can be configured with validation parameters provided by the user and indicated by the user input. In certain embodiments, a customized validator can be selected and configured with either or both one or more custom validation parameters and one or more custom validation routines. An applicable engine for selecting a validator, such as the validator selection engines described herein, can select a validator to use in validating the data based on the user input.
At block 506, the validator is applied to the data to determine if one or more statistics generated through application of the validator to the data are valid according to the validator. For example, one or more statistics can be extracted from the data based on one or more validation parameters of the validator. Further in the example, the one or more statistics can be determined to be valid or invalid based on one or more validation routines associated with the validator. An applicable engine for applying a validator to data, such as the validator application engines described herein, can apply the validator to the data to determine if one or more statistics generated through application of the validator to the data are valid according to the validator.
At block 508, the data set is flagged as valid or invalid based on whether at least one of the one or more statistics are found to be invalid according to the validator. For example, if a number of the one or more statistics greater than a threshold amount are found to be invalid, then the data set can be flagged as invalid. An applicable engine for flagging a data set as valid or invalid, such as the data quality flagging engines described herein, can flag the data set as valid or invalid based on whether at least one of the one or more statistics are found to be invalid according to the validator.
At block 510, a data quality report indicating whether the data set is valid or invalid as determined through application of the validator to the data is selectively presented to the user. A data quality report can be presented to the user through an applicable graphical user interface, such as the graphical user interfaces described herein. An applicable engine for generating a data quality report, such as the data quality report generation engines described herein, can selectively present to the user a data quality report indicating whether the data set is valid or invalid as determined through application of the validator to the data.
The techniques described herein are implemented by one or more special-purpose computing devices. The special-purpose computing devices may be hard-wired to perform the techniques, or may include circuitry or digital electronic devices such as one or more application-specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs) that are persistently programmed to perform the techniques, or may include one or more hardware processors programmed to perform the techniques pursuant to program instructions in firmware, memory, other storage, or a combination. Such special-purpose computing devices may also combine custom hard-wired logic, ASICs, or FPGAs with custom programming to accomplish the techniques. The special-purpose computing devices may be desktop computer systems, server computer systems, portable computer systems, handheld devices, networking devices or any other device or combination of devices that incorporate hard-wired and/or program logic to implement the techniques.
Computing device(s) are generally controlled and coordinated by operating system software, such as iOS, Android, Chrome OS, Windows XP, Windows Vista, Windows 7, Windows 8, Windows Server, Windows CE, Unix, Linux, SunOS, Solaris, iOS, Blackberry OS, VxWorks, or other compatible operating systems. In other embodiments, the computing device may be controlled by a proprietary operating system. Conventional operating systems control and schedule computer processes for execution, perform memory management, provide file system, networking, I/O services, and provide a user interface functionality, such as a graphical user interface (“GUI”), among other things.
The computer system 700 also includes a main memory 706, such as a random access memory (RAM), cache and/or other dynamic storage devices, coupled to bus 702 for storing information and instructions to be executed by processor 704. Main memory 706 also may be used for storing temporary variables or other intermediate information during execution of instructions to be executed by processor 704. Such instructions, when stored in storage media accessible to processor 704, render computer system 700 into a special-purpose machine that is customized to perform the operations specified in the instructions.
The computer system 700 further includes a read only memory (ROM) 708 or other static storage device coupled to bus 702 for storing static information and instructions for processor 704. A storage device 710, such as a magnetic disk, optical disk, or USB thumb drive (Flash drive), etc., is provided and coupled to bus 702 for storing information and instructions.
The computer system 700 may be coupled via bus 702 to a display 712, such as a cathode ray tube (CRT) or LCD display (or touch screen), for displaying information to a computer user. An input device 714, including alphanumeric and other keys, is coupled to bus 702 for communicating information and command selections to processor 704. Another type of user input device is cursor control 716, such as a mouse, a trackball, or cursor direction keys for communicating direction information and command selections to processor 704 and for controlling cursor movement on display 712. This input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allows the device to specify positions in a plane. In some embodiments, the same direction information and command selections as cursor control may be implemented via receiving touches on a touch screen without a cursor.
The computing system 700 may include a user interface module to implement a GUI that may be stored in a mass storage device as executable software codes that are executed by the computing device(s). This and other modules may include, by way of example, components, such as software components, object-oriented software components, class components and task components, processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables.
In general, the word “module,” as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, possibly having entry and exit points, written in a programming language, such as, for example, Java, C or C++. A software module may be compiled and linked into an executable program, installed in a dynamic link library, or may be written in an interpreted programming language such as, for example, BASIC, Perl, or Python. It will be appreciated that software modules may be callable from other modules or from themselves, and/or may be invoked in response to detected events or interrupts. Software modules configured for execution on computing devices may be provided on a computer readable medium, such as a compact disc, digital video disc, flash drive, magnetic disc, or any other tangible medium, or as a digital download (and may be originally stored in a compressed or installable format that requires installation, decompression or decryption prior to execution). Such software code may be stored, partially or fully, on a memory device of the executing computing device, for execution by the computing device. Software instructions may be embedded in firmware, such as an EPROM. It will be further appreciated that hardware modules may be comprised of connected logic units, such as gates and flip-flops, and/or may be comprised of programmable units, such as programmable gate arrays or processors. The modules or computing device functionality described herein are preferably implemented as software modules, but may be represented in hardware or firmware. Generally, the modules described herein refer to logical modules that may be combined with other modules or divided into sub-modules despite their physical organization or storage.
The computer system 700 may implement the techniques described herein using customized hard-wired logic, one or more ASICs or FPGAs, firmware and/or program logic which in combination with the computer system causes or programs computer system 700 to be a special-purpose machine. According to one embodiment, the techniques herein are performed by computer system 700 in response to processor(s) 704 executing one or more sequences of one or more instructions contained in main memory 706. Such instructions may be read into main memory 706 from another storage medium, such as storage device 710. Execution of the sequences of instructions contained in main memory 706 causes processor(s) 704 to perform the process steps described herein. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions.
The term “non-transitory media,” and similar terms, as used herein refers to any media that store data and/or instructions that cause a machine to operate in a specific fashion. Such non-transitory media may comprise non-volatile media and/or volatile media. Non-volatile media includes, for example, optical or magnetic disks, such as storage device 710. Volatile media includes dynamic memory, such as main memory 706. Common forms of non-transitory media include, for example, a floppy disk, a flexible disk, hard disk, solid state drive, magnetic tape, or any other magnetic data storage medium, a CD-ROM, any other optical data storage medium, any physical medium with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, NVRAM, any other memory chip or cartridge, and networked versions of the same.
Non-transitory media is distinct from but may be used in conjunction with transmission media. Transmission media participates in transferring information between non-transitory media. For example, transmission media includes coaxial cables, copper wire and fiber optics, including the wires that comprise bus 702. Transmission media can also take the form of acoustic or light waves, such as those generated during radio-wave and infra-red data communications.
Various forms of media may be involved in carrying one or more sequences of one or more instructions to processor 704 for execution. For example, the instructions may initially be carried on a magnetic disk or solid state drive of a remote computer. The remote computer can load the instructions into its dynamic memory and send the instructions over a telephone line using a modem. A modem local to computer system 700 can receive the data on the telephone line and use an infra-red transmitter to convert the data to an infra-red signal. An infra-red detector can receive the data carried in the infra-red signal and appropriate circuitry can place the data on bus 702. Bus 702 carries the data to main memory 706, from which processor 704 retrieves and executes the instructions. The instructions received by main memory 706 may retrieves and executes the instructions. The instructions received by main memory 706 may optionally be stored on storage device 710 either before or after execution by processor 704.
The computer system 700 also includes a communication interface 718 coupled to bus 702. Communication interface 718 provides a two-way data communication coupling to one or more network links that are connected to one or more local networks. For example, communication interface 718 may be an integrated services digital network (ISDN) card, cable modem, satellite modem, or a modem to provide a data communication connection to a corresponding type of telephone line. As another example, communication interface 718 may be a local area network (LAN) card to provide a data communication connection to a compatible LAN (or WAN component to communicated with a WAN). Wireless links may also be implemented. In any such implementation, communication interface 718 sends and receives electrical, electromagnetic or optical signals that carry digital data streams representing various types of information.
A network link typically provides data communication through one or more networks to other data devices. For example, a network link may provide a connection through local network to a host computer or to data equipment operated by an Internet Service Provider (ISP). The ISP in turn provides data communication services through the world wide packet data communication network now commonly referred to as the “Internet”. Local network and Internet both use electrical, electromagnetic or optical signals that carry digital data streams. The signals through the various networks and the signals on network link and through communication interface 718, which carry the digital data to and from computer system 700, are example forms of transmission media.
The computer system 700 can send messages and receive data, including program code, through the network(s), network link and communication interface 718. In the Internet example, a server might transmit a requested code for an application program through the Internet, the ISP, the local network and the communication interface 718.
The received code may be executed by processor 704 as it is received, and/or stored in storage device 710, or other non-volatile storage for later execution.
Each of the processes, methods, and algorithms described in the preceding sections may be embodied in, and fully or partially automated by, code modules executed by one or more computer systems or computer processors comprising computer hardware. The processes and algorithms may be implemented partially or wholly in application-specific circuitry.
The various features and processes described above may be used independently of one another, or may be combined in various ways. All possible combinations and sub-combinations are intended to fall within the scope of this disclosure. In addition, certain method or process blocks may be omitted in some implementations. The methods and processes described herein are also not limited to any particular sequence, and the blocks or states relating thereto can be performed in other sequences that are appropriate. For example, described blocks or states may be performed in an order other than that specifically disclosed, or multiple blocks or states may be combined in a single block or state. The example blocks or states may be performed in serial, in parallel, or in some other manner. Blocks or states may be added to or removed from the disclosed example embodiments. The example systems and components described herein may be configured differently than described. For example, elements may be added to, removed from, or rearranged compared to the disclosed example embodiments.
Conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment.
Any process descriptions, elements, or blocks in the flow diagrams described herein and/or depicted in the attached figures should be understood as potentially representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of the embodiments described herein in which elements or functions may be deleted, executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those skilled in the art.
It should be emphasized that many variations and modifications may be made to the above-described embodiments, the elements of which are to be understood as being among other acceptable examples. All such modifications and variations are intended to be included herein within the scope of this disclosure. The foregoing description details certain embodiments of the invention. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the invention can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the invention with which that terminology is associated. The scope of the invention should therefore be construed in accordance with the appended claims and any equivalents thereof.
Certain embodiments are described herein as including logic or a number of components, engines, or mechanisms. Engines may constitute either software engines (e.g., code embodied on a machine-readable medium) or hardware engines. A “hardware engine” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware engines of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware engine that operates to perform certain operations as described herein.
In some embodiments, a hardware engine may be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware engine may include dedicated circuitry or logic that is permanently configured to perform certain operations. For example, a hardware engine may be a special-purpose processor, such as a Field-Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). A hardware engine may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware engine may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, hardware engines become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware engine mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.
Accordingly, the phrase “hardware engine” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. As used herein, “hardware-implemented engine” refers to a hardware engine. Considering embodiments in which hardware engines are temporarily configured (e.g., programmed), each of the hardware engines need not be configured or instantiated at any one instance in time. For example, where a hardware engine comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware engines) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware engine at one instance of time and to constitute a different hardware engine at a different instance of time.
Hardware engines can provide information to, and receive information from, other hardware engines. Accordingly, the described hardware engines may be regarded as being communicatively coupled. Where multiple hardware engines exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware engines. In embodiments in which multiple hardware engines are configured or instantiated at different times, communications between such hardware engines may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware engines have access. For example, one hardware engine may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware engine may then, at a later time, access the memory device to retrieve and process the stored output. Hardware engines may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).
The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented engines that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented engine” refers to a hardware engine implemented using one or more processors.
Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented engines. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an Application Program Interface (API)).
The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processors or processor-implemented engines may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the processors or processor-implemented engines may be distributed across a number of geographic locations.
Throughout this specification, plural instances may implement components, operations, or structures described as a single instance. Although individual operations of one or more methods are illustrated and described as separate operations, one or more of the individual operations may be performed concurrently, and nothing requires that the operations be performed in the order illustrated. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as a single component may be implemented as separate components. These and other variations, modifications, additions, and improvements fall within the scope of the subject matter herein.
Although an overview of the subject matter has been described with reference to specific example embodiments, various modifications and changes may be made to these embodiments without departing from the broader scope of embodiments of the present disclosure. Such embodiments of the subject matter may be referred to herein, individually or collectively, by the term “invention” merely for convenience and without intending to voluntarily limit the scope of this application to any single disclosure or concept if more than one is, in fact, disclosed.
The embodiments illustrated herein are described in sufficient detail to enable those skilled in the art to practice the teachings disclosed. Other embodiments may be used and derived therefrom, such that structural and logical substitutions and changes may be made without departing from the scope of this disclosure. The Detailed Description, therefore, is not to be taken in a limiting sense, and the scope of various embodiments is defined only by the appended claims, along with the full range of equivalents to which such claims are entitled.
It will be appreciated that an “engine,” “system,” “data store,” and/or “database” may comprise software, hardware, firmware, and/or circuitry. In one example, one or more software programs comprising instructions capable of being executable by a processor may perform one or more of the functions of the engines, data stores, databases, or systems described herein. In another example, circuitry may perform the same or similar functions. Alternative embodiments may comprise more, less, or functionally equivalent engines, systems, data stores, or databases, and still be within the scope of present embodiments. For example, the functionality of the various systems, engines, data stores, and/or databases may be combined or divided differently.
“Open source” software is defined herein to be source code that allows distribution as source code as well as compiled form, with a well-publicized and indexed means of obtaining the source, optionally with a license that allows modifications and derived works.
The data stores described herein may be any suitable structure (e.g., an active database, a relational database, a self-referential database, a table, a matrix, an array, a flat file, a documented-oriented storage system, a non-relational No-SQL system, and the like), and may be cloud-based or otherwise.
As used herein, the term “or” may be construed in either an inclusive or exclusive sense. Moreover, plural instances may be provided for resources, operations, or structures described herein as a single instance. Additionally, boundaries between various resources, operations, engines, engines, and data stores are somewhat arbitrary, and particular operations are illustrated in a context of specific illustrative configurations. Other allocations of functionality are envisioned and may fall within a scope of various embodiments of the present disclosure. In general, structures and functionality presented as separate resources in the example configurations may be implemented as a combined structure or resource. Similarly, structures and functionality presented as a single resource may be implemented as separate resources. These and other variations, modifications, additions, and improvements fall within a scope of embodiments of the present disclosure as represented by the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
Conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment.
Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred implementations, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed implementations, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
This application is a continuation of U.S. Ser. No. 15/670,304, filed Aug. 7, 2017, which claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application Ser. No. 62/483,815, filed Apr. 10, 2017, the content of which is hereby incorporated by reference in its entirety.
