Adjusting the base form set's data sources

Warnung
titleImportant

Before working on a data source: create a backup!

Importing the base form set delivers a data source for each form. SQL knowledge (depending on the DBMS) is helpful for adjustments.

Do not change alias names

On the right of a data source are the attributes' alias names. These should not be changed – otherwise the change must also be applied to the form template.

Relationship data source ↔ form

The data source attribute is transferred into the form via its name. If an alias is given, exactly that must be used in the form. In the base form set, alias names should always be assigned.
