Data Model pane
The Data Model pane displays the result of all the preparations and extractions of the extraction workflow. The pane displays the content of a single record within the record set at a time.
Data is displayed as a tree view, with the root level being the record table. On the level below that are detail tables, and a detail table inside a detail table is called a nested table.
The Data Model is also used as a navigation tool between records and in all detail tables.
Data Model toolbar buttons
-
: Import Data Model: Click to browse to a Data Model File and import it. Importing a Data Model File displays the file's data model structure into the Data Model Pane, with optional sample data for each field. -
: Export Data Model: Click to browse to a location to save the Data Model File and save it. -
: Synchronize Data Model: Click to synchronize the data model with the one currently loaded in the open Data Mapping Configuration. Disabled if no configuration is currently open. -
: Show the ExtraData field. Note that this field is not meant to be filled via an extraction. It is meant to be used in a Workflow configuration to add data to the Data Model; see Adding fields and data via Workflow. - Minimize/Maximize: Click to minimize or maximize the pane. See Moving and Merging Panes.
Data Model contextual menu
The Data Model is generally constructed by extracting data; see Extracting data.
It is however possible to modify the Data Model, even if no data is present in the pane. To do
this, open the contextual menu within the pane itself by right-clicking on something in the Data Model pane. Depending on where you've clicked, it can contain the following options:
- Add Field: Click to add a new field at the current level (record or detail table). Enter the field name in the dialog; if you want you can change the field's data type and set a default value. Then click OK to add it to the Data Model.
- Add Table: Click to add a new detail table at the current level (record or existing detail table). Enter the table name in the dialog and click OK to add it.
Rename, Delete and Set Type are only available for Data Model fields or detail tables that are not filled via an extraction.
Fields and detail tables that are filled via an Extract step are to be changed (renamed, deleted etc.) via the properties of that Extract step; see: Editing fields and Renaming a detail table.
Fields and detail tables that are filled via an Extract step are to be changed (renamed, deleted etc.) via the properties of that Extract step; see: Editing fields and Renaming a detail table.
- Rename: Click to rename the selected table or field. Enter the new name and click OK to rename.
- Delete: Click to delete the selected table or field.
- Set Type: Use the list to select the field type (see Data types).
- Default Value: Click to set the default value for a field. This value is used if no extraction is present, or if an extraction attached to this field returns no value.
- Collapse Fields: Collapse the fields in the selected level.
- Expand Fields: Clicking the icon that represents collapsed fields (for example:
) enables this menu item. It is used to expand the fields on one level. - Collapse All Fields: Collapse the fields on the record level and in all detail tables.
- Expand All Fields: Expand the fields on the record level and in all detail tables.
Field display
Fields in the Data Model pane are displayed in specific ways to simplify comprehension of the display data:
- Value: The current value of the extracted field, based on the record shown in the Data Viewer.
- The column on the left displays the name of the field.
- The column on the right displays the current value of the extracted field based on the record shown in the Data Viewer, if an Extract step has an extraction for this field (see Extracting data).
- The icon to the left of the name indicates the data Type of the field (see Data types).
- A field name with an asterisk to the right indicates that this field is part of an imported Data Model file.
- A field with a grey background indicates this Data Model field does not have any attached extracted data.
- A field with a white background indicates that the field has attached extracted data but the step extracting the data is not currently selected.
- A field with a blue background indicates that the field has attached extracted data and the step extracting the data is currently selected.
Record navigation
Records can be navigated via the Data Model pane. The default record level navigates between records both in the Data Model pane and the Data Viewer, while each detail table has a similar navigation that influences that table and each detail table under it.
- Expand/Contract: Click to hide or show any fields or tables under the current table level.
- Table Name: Displays the name of the table as well as the number of records at that level (in [brackets]). At the record level this is the number of records. In other levels it represents the number of entries in a detail table.
- Number of Records: The number of available records in the active data sample. This is affected by the Boundary settings (see Record boundaries and Settings pane) and the Preprocessor step (Preprocessor step).
- First Record: Go to the first record in the data sample. This button is disabled if the first record is already shown.
- Previous Record: Go to the previous record in the data sample. This button is disabled if the first record is shown.
- Current Record: Displays the current record or table entry. Type a record number and press the Enter key to display that record. The number has to be within the number of available records in the data sample.
- Next Record: Go to the next record in the data sample. This button is disabled if the last record is shown.
- Last Record: Go to the last record in the data sample. This button is disabled if the last record is already shown. If a record limit is set in the Settings pane (Settings pane) the last record will be within that limit.
