Mapping groups

A mapping group contains mapped elements by a target table (in a relational database). There will be one query that is generated for each mapping group. When you create a mapping, the mapping editor tries to include that mapping in an existing mapping group. If there is no appropriate mapping group the mapping editor creates a new mapping group.

A mapping group using a relational schema on the target side can span one table.

A mapping group is created automatically by the mapping editor when needed, but you can also create a mapping group manually. You can also add a new complex element or a table to an existing mapping group. For example, if the generated mapping group does not include a table that is required based on some database constraint, then you can manually add the table to the mapping group.
