A user system 10 for importing an processing data is schematically shown in
A table structure and method for importing and processing large amounts of data sets into said user system 10 will be described in the following. As a preferred embodiment, the importing and processing of address data in a system will be described hereinafter.
External data comprising a plurality of data sets to be imported into a system are provided on an electronic storage medium, like a CD, or are received via ISDN, email, and so on. The data sets are provided in a predefined format in a data file e.g. ASCII, Excel, or dBase. The data sets comprise data segments of different categories. For address data such categories could be first name, last name, street, house number, city, etc. The segments of a data set are separated by a separator in the data file. The separator can be e.g. comma, semicolon, tab or any other character.
External data to be imported into the system are first uploaded without any further processing (step S10). The data sets uploaded in the user system are referred to as “data list”. The uploaded data sets are mapped (step S20). In particular the data structure of the uploaded data sets is transferred to the data structure of the system (to be described later). After mapping the data sets several checks are performed on the data sets in order to verify if particular properties of the data sets are correct. In the present case, as address data sets are used, a postal check (step S30) and a duplicate check (step S40) are performed. In the postal check it is verified whether the address data provided is correct with respect to general properties, e.g. it is checked whether the postal code correctly corresponds to the city given in one data set.
During the duplicate check step, it is checked whether duplicate data sets, i.e. substantially identical data sets or data sets having a specified (predetermined or predeterminable) range of identical data fields are present. During this check it can be verified whether a newly imported data set is substantially identical to a data set already present in the system or whether two newly imported data sets are identical. The duplicate check can e.g. be performed by comparing the components of the one data set (last name, first name, street, . . . ) with the same components of another data set.
After having performed the various checks, the imported data sets can be further processed (step S50) as will be described later.
In the following, a table structure used for importing and processing data and/or data sets will hereinafter be referred to as a “staging area”.
The staging area comprises a plurality of tables into which data segments of the imported data sets and/or additional information relating to the data list is written.
The external data stored on a data storage medium is read line by line (data set by data set) and stored in table CRMD_MKTLIST_C. During this step, the data is not processed in any way. This means that in CRMD_MKTLIST_C the data is stored in a form similar to the form of the provided data in the data file. The data segments separated by the separator are written into the table CRMD_MKTLIST_C substantially without an processing. Thus the data sets as a whole are transferred from the data storage medium to the table CRMD_MKTLIST_C without being split up into separate parts.
The data stored in CRMD_MKTLIST_C is then mapped. During the mapping step the data sets stored in CRMD_MKTLIST_C are each divided up, whereby one or more segments of each data set are stored e.g. in either of tables CRMD_MKTLIST_ADR, CRMD_MKTLIST_ORG, CRMD_MKTLIST_PER, CRMD_MKTLIST_CEN. In CRMD_MKTLIST_ADR data segments of each data set relating to address properties (e.g. street, postal code, city, . . . ) of the data sets are stored. In CRMD_MKTLIST_ORG data segments of each data set relating to the data set's organizational properties (e.g. company name, . . . ) are stored. In CRMD_MKTLIST_PER data segments of each data set relating to the person (e.g. first name, last name, age, sex, . . . ) are stored. In CRMD_MKTLIST_CEN data segments of each data set relating to containing additional information (e.g. contact person of a company, . . . ) are stored.
If the data sets relate to other types of data, other suitable tables can be used.
A table CRMD_MKTLIST_E is provided in which error messages for errors which occur during the processing of the data are logged.
Furthermore, there is provided a plurality of tables which form a so called “administrative area”. In the present system the following tables are provided:
In CRMD_MKTLIST_H header information and attributes (e.g. origin of the data, type of the data, costs) relating to the list are stored. In CRMD_MKTLIST_T additional information (e.g. short description, language dependent) relating to the list is stored. In CRMD_MKTLIST_PH package header information and attributes is stored, e.g. the mapping format used or the name of the provided file containing the data sets to be imported. In CRMD_MKTLIST_S the steps which have already been processed for a specific data list are indicated. In CRMD_MKTLIST_L builds the connection between the header and the list itself. In particular a reference to CRMD_MKTLIST_H is stored in this table. In CRMD_MKTLIST_I a link or reference to a created data object (to be described later) is stored for each data set.
In the following, examples of the above mentioned tables are shown:
A graphical user interface for operating the staging area will be described with reference to
The user interface comprises a field 30 for inputting an ID of a list to be created and a field 32 for inputting a description of the list. Furthermore, the user interface comprises a plurality of tab strips 34-42 for selecting specified input screens described hereinafter.
If the user wants to upload a new data file he must create a new data list. The user enters an ID of the data list in field 30 (in the present case: PERSON_LIST) and a description of the list in field 32. On tab strip 32 the user enters or can enter attributes such as the origin in field 44, the type in field 46, the costs in field 48, the permitted number of uses in field 50 or permitted end of use date in field 52 (if the data sets can only be used for a predefined number of times and/or a predefined usage period, to be described later), recommended end of use date in field 54 and/or the gross number in field 56 (=number of expected data sets in the file). This information input in region 62 is stored in tables CRMD_MKTLIST_H and CRMD_MKTLIST_T.
Furthermore, the user enters the file name (with complete path) in field 58 and the field separator used in the data file to be imported (comma, semicolon, tab, other character) in field 60. A so called “package” is created and the information input in region 64 is stored in table CRMD_MKTLIST_PH.
On tab strip 36 the user can mark in the fields 68-74 the steps or processing that should be processed within one background job, i.e. in one run. In the shown screen, the user can select one, several or all of ‘Upload File’ (field 66), ‘Map Data’ (field 68), ‘Postal Check’ (field 70), ‘Duplicate Check’ (field 72), and two steps for further processing (fields 74, 76) (‘Business Partner Creation’ and ‘Target Group Creation’).
If the step ‘Map Data’ (field 66) is marked a mapping format must be given (to be described later).
The user can specify in field 80 the start type, i.e. whether the processing is to start immediately or at a specified later time.
If the user presses the save button 78, the entered data is saved.
The input data is then written into tables CRMD_MKTLIST_PH and CRMD_MKTLIST_L by the system. Table CRMD_MKTLIST_S contains all steps for the package, wherein the status of every step is initial.
In the following several examples for processing are given.
The user marks the upload step (field 66), gives a start date/time (field 80) and saves the list (button 78). The file is read from application server and its content is stored in table CRMD_MKTLIST_C. in particular the data sets stored in the data file are read data set by data set and written into table CRMD_MKTLIST_C.
In table CRMD_MKTLIST_S the status of step U (‘upload’) is updated. If errors occur the step can be repeated. In that case only those data sets of the file are processed which were not transferred to CRMD_MKTLIST_C earlier. If the step was processed without any error it cannot be repeated again.
The user marks the mapping step (field 68), gives a start date/time (field 80) and saves the list (button 78). Once the input by the user is terminated and/or the start time is reached, the processing starts. The previously uploaded data is read from table CRMD_MKTLIST_C data set by data set, mapped and stored in the other tables of the staging area:
In particular, an iterative processing takes place in which respective data segments of each data set are read and subsequently written into one of the above tables.
In table CRMD_MKTLIST_S the status of step M (‘mapping’) is updated. In table CRMD_MKTLIST_I the items are inserted. If errors occur the step can be repeated for all data sets or only for the erroneous. At start of the repetition for all data sets the entries in CRMD_MKTLIST_E, CRMD_MKTLIST_ADR, CRMD_MKTLIST_ORG, CRMD_MKTLIST_PER and CRMD_MKTLIST_CEN are deleted for the repeated data sets. New entries in CRMD_MKTLIST_E, CRMD_MKTLIST_ADR, CRMD_MKTLIST_ORG, CRMD_MKTLIST_PER and CRMD_MKTLIST_CEN are created during the processing. The entries in CRMD_MKTLIST_I are updated only.
In case of repetition for erroneous data sets, only those data sets that are marked as erroneous (in table CRMD_MKTLIST_E) and those data sets that were not processed in previous execution are processed again. Entries in CRMD_MKTLIST_E are deleted just before creating new entries.
The user marks the step for postal check (field 68), gives a start date/time (field 80) and saves the list (button 78). Once the input by the user is terminated and/or the start time is reached, the processing starts. The previously mapped data is read from tables of the staging area
If errors occur the step can be repeated for all data sets s or only for the erroneous. At start of the repetition the entries in CRMD_MKTLIST_E are deleted for the repeated data sets. New entries in CRMD_MKTLIST_E are created during the processing. The entries in CRMD_MKTLIST_I are updated only.
The user marks the step for duplicate check (field 72), gives a start date/time (field 80) and saves the list (button 78). Once the input by the user is terminated and/or the start time is reached, the processing starts. The previously mapped data is read from tables of the staging area
If errors occur the step can be repeated for all data sets or only for the erroneous. At start of the repetition the entries in CRMD_MKTLIST_E are deleted for the repeated data sets. New entries in CRMD_MKTLIST_E are created during the processing. The entries in CRMD_MKTLIST_I are updated only.
After the marked steps are processed a traffic light 84-92 shows if errors occurred. By pressing the button associated with the traffic light 84-92 a popup window with detailed messages appears (see e.g.
The processing of the steps can be repeated, the user must mark the step again. For some steps the user can mark a second flag 94. If this flag 94 is marked all data sets are processed again, otherwise only the erroneous data sets are processed again.
A summary log with status information of all processed steps can be opened by pressing the log button 96 (see
In
The processed data stored in the tables of the staging area can be use used in the user system for creating data objects for each data set. These data objects can then be further processed in the user system.
If a data object is created for a data set, a reference to the created data object is stored in the table CRMD_MKTLIST_I. The created data object is preferably stored centrally in the user system to be accessible for a plurality of applications. Table CRMD_MKTLIST_I establishes a link between the data sets stored in the staging area and the centrally stored data object.
In the following a User Interface for mapping the read data sets stored in table CRMD_MKTLIST_C will be described with reference to
Before a data list can be mapped a mapping format must be defined.
In the general section M10 there is provided a field 98 for inputting an ID of a mapping format to be used. A predefined mapping format previously stored can be used. Alternatively, a new mapping format can be created or an existing mapping format can be edited. Furthermore, in the field 100 a text description of the mapping format can be entered.
The file name of the imported file is entered in the filed 102. Furthermore, the type of field separator is to be chosen in field 104.
Moreover, there are table controls M12 and M14 placed side to side. The table control M12 on the left (segment display section) has three fields 106, 108, 110 in which a position (column number of data segment in the imported file), a file preview (data segment of one data set in the file) and/or the target field name which indicates the target field to which the respective data segment is to be associated are displayed, respectively.
When creating a new mapping format this table control M12 is empty. When the data file for which the mapping format is to be used is selected, the file contents is read depending on the file separator selected. If a correct separator is selected the data is read and shown to the user in table control M12 with each row R1, R2, R3 in the table control M12 showing individual column values (data segments) of one data set of the data file in field 108. Since its only a preview, the first line of the data set is read and placed in the table control M12. If the user had chosen an invalid separator, the whole data set (first line) is shown in one single row (the first row R1 of the table control M12).
The table control M14 on the right (target display section) shows possible target fields defined in the staging area and their description. In the left table control M12 for every column (position) in the file a target field can be assigned in field 110.
A category column (field 112) appears in this control M14, which clearly demarcates the target fields which belong to an organization, organization address, person, person address and contact person function, in the case if address data are used. In case other types of data are used, other specifications can be given for the target fields. This table control displays only target fields.
Since now the user knows the file content for which the mapping has to be done, he can choose the target field by marking one of rows R4-R6 on the table control M14 and the source field by marking one of rows R1-R3 on the table control M12) and press the move button 114 which appears between these controls M12, M14.
Some target fields only allow predefined values defined in a customizing table. For those target fields a value mapping can be defined as will be described hereinafter. For the value assignment the tab 116 is provided.
As shown in
Moreover, it is possible to assign a plurality of expressions used in the imported data sets to a specified (predetermined or predeterminable) value in the user system. A table control M16 is provided where the user can assign multiple values to the possible values of the mapped field. In the present example, the expressions “Mr.”, “Mr”, “Mister” and “MR” are all assigned to the value 0002 representing “Mr.” in the user system.
Furthermore, there can be provided a field in which all possible values of a particular data segment of all data sets of a file for which value mapping is to be provided are displayed (not shown in
For those target fields that should have the same value for all data sets in the file a constant assignment can be defined.
The constant assignment can be used if all data sets of the data list should have the same value for a particular field. For example a data list has data sets only from the United States but the country information is not part of the file. The country field is assigned to the mapping format and the constant value US is assigned to this field.
On tab strip 118 in field 124 the user can input the constant value to be assigned to all data sets.
For those target fields that need a more complex mapping algorithm, a code can be programmed in field 126. In the shown user interface a so called “ABAP code” (Advanced Business Application Programming) can be defined.
The user interface does not allow the user to select this tab 120 unless and until the user selects a mapped field from the table control M14, which holds the mapping fields. Now, the user can see the names of the input structure and the output structure (this is like input parameter and output parameter of a function module). The user can write executable routines in ABAP Code for this mapping field in this control. Care must be taken that the values that come in, are always in the input parameter and the output after the conversion should be assigned to the output parameter.
In the present example, the file contains no column with language information. Via coding the language information is derived from the country information.
If global variables are needed for the ABAP coding they can be defined in tab strip 122 in field 128.
Data sets imported into the system can have a specified (predetermined or predeterminable) property. Such a property can be associated with a further constriction, e.g. that the data sets can only be used a specified (predetermined or predeterminable) number of times. In the present case, the specified property data can e.g. be that the data sets are rented from a data provider. Such rented data in general only have a limited number of uses and/or a limited time frame in which they can be used by the user. Therefore, the data have to be marked accordingly with a flag. In the present case, a so called “rented flag” is used. If a specified (predetermined or predeterminable) event occurs, e.g. a contacted person reacts to the an activity, the specified property of the data can be changed, i.e. the flag deleted.
In order to be able to check if accordingly marked data sets have already been used the maximum number of times, and can thus not be used again, or if the data set can still be used, a counter is associated with each data set. The counter indicates how many times the respective data set has already been used.
The checks to determine whether a data set can be used a further time have to be performed before the respective data set is used. However, such checks need only to be done if the data sets still has a specified property, i.e. is marked a rented in the present case.
In the following it will be described with reference to
In step R10 the processing of a specified data set starts. In step R12 it is checked whether the respective data set has a specified property. In case the data set does not have the specified property (“no” in step R12), the data set can be used without any further checks and the process proceeds to step R22. In case the data set has the specified property (“yes” in step R12), a check is made whether the maximum usage time for the data set has elapsed (step R14). If the maximum usage time for the data set has elapsed (“yes” in step R14), the data set cannot be used and the process proceeds to step R16. If the maximum usage time for the data set has not yet elapsed (“no” in step R14), a check is made whether the number of the counter associated with the data set is equal or larger than the maximum number of usage times of the data set (step R18). If the counter is equal or larger than the maximum number of usage times (“yes” in step R18), the data set cannot be used and the process proceeds to step R16. If the counter is less than the maximum number of usage times (“no” in step R18), i.e. the data set can still be used, the counter is increased (step R20) and the data set is used (step R22).
All actions already performed with a particular data set a separately stored in an action table or list so that each action can be tracked. Furthermore, in one preferred embodiment, the value of the counter is generated by summing up the number of already performed actions for a particular data set. By doing so, the data consistency can be enhanced as wrong values due to e.g. a system crash can be substantially avoided. In particular if e.g. an action is to take place, but the processing of the action is interrupted due to external factors.
If the action to be done with the data set cannot be executed properly, the data set can be used again, i.e. the counter must be decreased. This can e.g. be done by provided a check of the action table.
In case a specified reaction can be tracked in response to an action executed with a data set, the specified property can be removed from the respective data set. In such a case, the data set can be used freely substantially without the necessity of any of the above checks to be done.
The data set can be used in different sections of the user system. As already mentioned above, the user system can comprise a first section for importing and processing the data sets and at least one second section in which the data sets are used for interaction with still other parts of the system. If the data sets have the above defined specified property, there are restrictions given with respect to their use, as already partly discussed above. In order to maintain a consistency of the data, the counter is preferably stored in the first section and all sections using respective data sets inquire with the first section whether a data set can be used or not if the data set has the specified property.
In case the maximum usage time of a data list has run up and some or all of the data sets of this list still have the specified property, in many cases the data sets need to be removed from the system. However, as discussed above, it is possible that the data sets are also used in other sections of the system. As a consequence, the data not only has to be deleted in the first section into which the data has been imported but also in the other sections where the data sets are used.
In the following, the basic process of deleting data sets having a specified property in the first section of the user system will be described with reference to
The deletion of a data list is started in step D10. This process is in particular started if the maximum usage time of a data list has expired.
In step D12 it is checked whether the data list has the specified property. In the present case this is a check whether the data list is rented or not. If the data list does not have the specified property (“no” in step D12), the data list does not have to be deleted (step D14). If the data list has the specified property (“yes” in step D12), step D16 is performed as long as the end of the list in not reached, i.e. as long as there are data sets in the data list.
In step D16 the following steps are performed preferably for each data set of the data list. The data set is read from the data list (step D18). It is checked, whether the read data set has the specified property (step D20). If the data set does not have the specified property (“no” in step D20), the data set does not have to be deleted (step D22). If data set has the specified property (“yes” in step D20), the data set is deleted in step D24. Furthermore, in this step an indicator or instruction set is sent to preferably all other sections of the system in which the data set is used. In the present case, the data sets are also used in the second section. Therefore an indicator is sent to the second section.
In the second section the indicator from the first section is received and the respective data set is anonymized, in particular the contents of the data set is filled with blank fields.
After having finished the processing described above, all data sets which had a specified property are removed from the system.
In the following, there will be given a description of a deletion process for the case in which data objects have been created from the data sets. In this case, all data from the staging area needs to be deleted. Furthermore, the created data objects having a specified property need to be deleted. A flow chart for such a deletion process is shown in
In step D100 the deletion of the data list is started and in step D102 all data sets are deleted from the staging area, i.e. the tables CRMD_MKTLIST_E, CRMD_MKTLIST_C, CRMD_MKTLIST_ORG, CRMD_MKTLIST_PER, CRMD_MKTLIST_ADR, CRMD_MKTLIST_CEN.
The data stored in CRMD_MKTLIST_H is read (step D104), i.e. the ID of the list to be deleted is read. In step D106 it is checked whether the data list has the specified property. In case the data list does not have the specified property (“no” in step D106), the process proceeds to step D118. In case the data list has the specified property (“yes” in step D106), the reference to the data objects is read from table CRMD_MKTLIST—I (step D108).
For every data object associated with the list to be deleted (step D110), it is determined whether the data object has the specified property (step D112). In case the data object does not have the specified property (“no” in step D112), the process proceeds to step D114 and the data object is not deleted. In case the data list has the specified property (“yes” in step D112), the data object is deleted. Furthermore, in this step an indicator is sent to preferably all other sections of the system in which the data set is used. In the present case, the data sets are also used in the second section. Therefore an indicator is sent to the second section. In the second section a similar processing to the one described with reference to
In step D118 the data in the tables CRMD_MKTLIST_S, CRMD_MKTLIST_L, CRMD_MKTLIST_PH are deleted. Then, the data in the table CRMD_MKTLIST_I is deleted (step D120). In the table CRMD_MKTLIST_H the delete flag is set (step D122).
After the deletion only the table CRMD_MKTLIST_H and CRMD_MKTLIST_T contain information about the deleted list.
The above description has been given for the importing and processing of address data set into a user system. However, other types of data can also be processes by the described structures. Such data could e.g. be measurement data which are to be evaluated in an evaluation system.
