Changing the Data Model
By adding fields to a Data Model, setting their type and entering a (default) value, you may
construct or modify a Data Model without having to create or open a data mapping
configuration. This is especially useful when a solution does not require a data mapping
configuration.
It isn't possible to enter data in a Data Model directly, but you could add JSON data (see
"Adding JSON sample data" on page794).
Modifying a Data Model can be done via the contextual menu. To open it, right-click the Data
Model.
l 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.
l 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.
l Add Group: Click to create a new group at the current level (record or existing group).
Enter the group name in the dialog and click OK to add it. Any selected fields will be
added to the group. (See also: "Ordering and grouping fields in the Data Model" on
page269.)
Note
Rename, Delete and Set Type are only available for newly added fields.
l Rename: Click to rename the selected table or field. Enter the new name and click OK to
rename.
l Delete: Click to delete the selected table or field.
l Set Type: Use the list to select the field type (see "Data types" on page286).
l Ungroup: Delete the selected group. The fields in the group will be moved up one level
in the Data Model.
l Default Value: Click to set the default value for a field.
l Move: Click to move the selected field within the current level (record or group) in the
Data Model. (See: "Ordering and grouping fields in the Data Model" on page269.)
