A physical data model is a database-specific model that represents relational data objects (for example, tables, columns, primary keys, and foreign keys) and their relationships. A physical data model can be used to generate DDL statements which can then be deployed to a database server.
In the workbench, you can create and modify data models by using the Data Project Explorer, the Properties view, or a diagram of the model. You can also analyze models and generate DDL.
To make it easier to work with other tools and other team members, you can annotate and print or save image files of diagrams and publish data models to the Web.
