Object Oriented Model mappings

Chapter 13 Creating Mappings

Object Oriented Model mappings

In an Object Oriented Model (OOM), you can create the following types of mappings:

Object to relational (O/R) mapping between OOM classes and PDM tables to manage the persistence of objects in a relational database. See Object to Relational (O/R) mapping.
Object to conceptual mapping between OOM classes and CDM entities to express a simple correspondence between objects in a Conceptual Data Model. See Object to conceptual mapping.

The following table shows all the allowed mappings with OOM objects:

Target OOM object	Source PDM object	Source CDM object
Class	Table	Entity
Class attribute	Table column	Entity attribute
Operation	SELECT or UPDATE queries associated with a table	—
Association	Reference, view reference, table or view	Association, relationship
