Source

The source datastores contain data used to load the target datastore. Two types of datastores can be used as a source of an interface:

• The datastores from the models,
• and temporary datastores target of an interface.

The source datastores of an interface can be filtered during the loading process, and must be put in relation through joins. Joins and filters can be recovered from the models definitions, and can also be defined for the interface. Mapping

The mapping defines the transformation rules on the sources enabling to generate data to load the target.

Target

The target datastore is the element that will be loaded by the interface. This datastore may be :

• permanent (defined in a Model)
• or temporary (created by the interface in the staging area).
