Information Objects as a Bridge

Actuate Information Objects act as a perfect bridge between the data layer and the presentation layer. They map the physical database fields to the logical fields of the generic schema described in Step 1. This is a very good alternative to the use of an alias in the SQL statement described in Step 1. Information Objects act as a separator between the data layer and presentation layer. When something changes in the data layer, only the Information Object needs to be modified, not all the report designs that use it as a data source. The following is an example Information Object that maps the physical database fields to our generic schema:



Information Objects that use the generic schema can be swapped into report designs for reuse of the presentation layer.
