Creating a project model
You may include an unlimited number of project models in a single SA encyclopedia. All of the project models in the same encyclopedia enjoy the benefits of a common shared data dictionary and access to the entity pool.
You may create a Project Data Model without creating a specific Entity Relation or IDEF1X diagram that represents it.
To create a Project Data Model
1 Click Dictionary > New Definition.
2 Select Project Data Model, and then click OK.
