Generating Database Tables from Entity Objects
You can create database tables from entity objects. Right-click the package that contains the entity objects and select Create Database Objects from the context menu. Then in the Create Database Objects dialog box, select the object to create. Another dialog box appears to confirm that you want to do this before proceeding.
Use caution when performing this generation, especially on entities that are based on existing tables. The feature does not generate a script to run later, but performs its operations directly against the database and drops existing tables.
