These operations, structural devices, acts and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.
Referring now to the drawings, in which like numerals represent like elements.
Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types. Other computer system configurations may also be used, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and the like. Distributed computing environments may also be used where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
Referring now to
The mass storage device 120 and its associated computer-readable media provide volatile and non-volatile storage for the computing device 100. The computer readable media may include any type of removable and/or non-removable media.
The computing device 100 operates in a networked environment using logical connections to remote computers through a network 112, such as the Internet. The computing device 100 may connect to the network 112 through a network interface unit 110 connected to the bus 116.
The computing device 100 may also include an input/output controller 114 for receiving and processing input from a number of devices, such as: a keyboard, mouse, electronic stylus and the like. Similarly, the input/output controller 114 may provide output to a display screen, a printer, or some other type of device (not shown).
As mentioned briefly above, a number of program modules and data files may be stored in the mass storage device 120 and RAM 106 of the computing device 100, including an operating system 122 suitable for controlling the operation of a networked computer. The mass storage device 120 and RAM 106 may also store one or more program modules. In particular, the mass storage device 120 and the RAM 106 may store a local component of a Database Management System (DBMS) 124.
The local component of the DBMS 124 includes functionality for presenting a customized parameter user interface for entering parameters in relation to a database search query. The customized parameter user interface provides parameter entry dialogs/windows in correlation to a data view (e.g., form or report) that is produced according to a database query. The parameters entered may allow for modification of the data view. The modification may occur without altering the original query statement. The modification may also occur by directly modifying the query statement. The persistence of the modification may be associated with the record source, a query object, and/or a parameter property. Also, the manager of the database may structure data views of a database to automatically include prompts for parameters before results are returned by the database. These prompts may be customized by the manager and may be provided according to dialogs such as pop-ups, pull-down menus, fly-outs, or a variety of other user interface components. Accordingly, an intuitive, efficient and modifiable data view is provided.
As used herein, “Control” generally refers to a child display frame an application uses in conjunction with another display frame to perform simple input and output (I/O) tasks. Controls are most often used within dialog boxes, but may also be used in other display frames. Controls within dialog boxes provide the user with the means to type text, choose options, and direct a dialog box to complete its action. Controls in other display frames provide a variety of services, such as letting the user choose commands, view status, and view and edit text. One example of a control is a right-click selection menu that presents a child display frame of an application's user interface.
“Data view” generally refers to a form, report and/or table that represents a collection of data from a database. The collection of data from the database may be provided in the form or report according to a database search query. The data view may be modified by the entry of any parameters according to the customized parameter user interface.
As used herein below, “Parameter” generally refers to any data value or set of data values associated with the data included in a data view. Entered parameters may modify a particular data view when entered according to the customized parameter user interface.
“Parameter entry prompt” generally refers to a user interface dialog that is provided for entry of a parameter in association with a data view. The user interface dialog may take the form of a display frame, pop-up, pull-down menu, fly-out, or a variety of other user interface components. Entry of the parameter in the parameter entry prompt may be provided as a text box entry, a pull-down selection box, or other types of data entry user interface components.
“Parameter filter property” (PFilter) generally refers to a property that corresponds to an entered parameter associated with a data view. The parameter filter property is added to the query statement according to a Boolean AND operation to modify the results included in the data view.
“Parameter form property” (PForm) generally refers to a property that when activated indicates that a customized parameter form is associated with a particular data view.
“Record source” generally refers to a stored property corresponding to the query statement that represents the data view. When a parameter is entered in accordance with the present disclosure, the parameter may be added according to a Boolean AND operation to the record source.
“Query statement” corresponds to the statement used for a query to the database that produces the data view. In a structured query language (SQL) database, the query statement corresponds to the SQL statement passed to the database engine for retrieving the database results corresponding to the data view.
In operation, data view browser 202 communicates between database engine 230 and the other functional blocks of DBMS 124 to provide a data view (e.g., a form or report, see
Data view browser 202 communicates any parameter requests 234 to parameter prompt module 204. Parameter prompt module 204 consults with property manager 208 to determine if a customized parameter form is associated with current data view. Property manager 208 accesses a list of properties (e.g., 214-220) in storage 212 to make the determination. Storage 212 may be a temporary or permanent storage and may correspond to system memory 104 or mass storage device 120 shown in
If the properties (e.g., 214-220) in mass storage device indicate that a customized parameter form is associated with the data view, functionality provided by customized parameter UI module 206 is used to display the customized parameter form in association with the data view. If however, the properties (e.g., 214-220) indicate that no customized parameter form is associated with the data view, a general parameter form is provided by parameter prompt module 204 to solicit entry of the requested parameter from the user.
The functional blocks described in
At operation 302, an object/view is being opened (e.g., a form or report) that returns the response to the query in a readily understandable format. While the report is being opened, processing continues with decision operation 304.
At decision operation 304, a determination is made whether a PFilter property is specified for the query. The PFilter property indicates a WHERE clause in the query, such that an additional filtering of the query is being requested. If no PFilter property is being specified, processing advances to operation 308. However, if a PFilter property is specified, processing continues to operation 306.
At operation 306, a PFilter clause corresponding to the specificed PFilter property is added to the query statement. For example, if the PFilter property is one that indicates an alphabet limitation of results beginning with the letter “A”, and the original query was for current customers, then a clause is added such that the resulting query is for customers that start with the letter “A”. Processing continues at operation 308.
At operation 308, the query statement is executed. While the query statement is executed, processing continues with decision operation 310.
At decision operation 310, a determination is made whether execution of the query statement requires a parameter for completion. If no parameter is required, then processing advances to operation 322. However, if a parameter is required to be entered, then processing moves to decision operation 312.
At decision operation 312, a determination is made whether a form has been specified already for use for requesting the entry of the parameter. In one embodiment, a parameter form is specified when indicated by a PForm property. If no form is specified, processing moves to operation 314.
At operation 314, a prompt is provided for entering the parameter that does not include the customizations available in a parameter form generated according to the present disclosure. Once the prompt is displayed, processing continues with decision operation 316.
If however, a parameter form is specified, processing continues with operation 318. At operation 318, the specified form is displayed for entry of the parameter. Once the specified form is displayed, processing continues with decision operation 316.
At decision operation 316, a determination is made whether the user has selected to cancel the query. The query can be canceled at any time at the user's selection. If the user has canceled the query, processing moves to operation 318. At operation 318, the opening of the object/view of the data is canceled, and processing ends.
If however, the query has not been canceled, processing moves to operation 320. At operation 320, the execution of the statement, modified with the entries of the parameters, is executed. The modification may occur without altering the original query statement. The modification may also occur by directly modifying the query statement. The persistence of the modification may be associated with the record source, a query object, and/or a parameter property. Processing continues at operation 322.
At operation 322, the results of the query are bound to the object/view and the results are shown as modified by the entered parameters. Once the object/view is displayed, process 300 ends, and processing move on to other tasks.
At operation 402, a command is received to add a parameter to a customized parameter form. The command may come from a pull down menu selection or other edit selection by the developer of the customized form. Processing continues with decision operation 404.
At decision operation 404, a determination is made whether the PFilter property already contains the parameter being added. If the PFilter property does not contain the parameter, processing moves to operation 406 where the parameter is added to PFilter property. If the PFilter property was already populated with the parameter or once the PFilter property is populated with the parameter, processing moves to decision operation 408.
At decision operation 408, a determination is made whether a PForm property indicates that a parameter form has been already designated for inclusion of the property. If no parameter form has already been generated, processing moves to operation 410 where a parameter form is created and the PForm property is set.
If the parameter form for inclusion of the parameter was already created, or once the parameter form is created, processing continues with operation decision operation 412.
At decision operation 412, a determination is made whether a control has been generated on the form for entry of the parameter. If no control is present, processing moves to operation 414 where a process is commenced for generating a control on the parameter form for entry of the parameter.
If a control was already generated, or once the control is generated, processing continues to operation 416. At operation 416, the object/view of the data with the added parameter may be displayed after execution of the query statement. Once the object/view is displayed, process 400 ends, and processing moves to other tasks.
The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
