Design Capture a.k.a. Reverse Engineer DB Admin is primarily used to reverse engineer an existing Oracle or non-Oracle database. When an existing database is reversed engineered, a Server Model is created and every object in the physical database is captured and documented in the Server Model. This would include such objects as tables and columns along with their properties and primary, unique, and foreign keys. Once the Server Model is created, the ERD can be generated.
Reverse engineering is done by the DBAs.
Verify with Data Administration that reverse engineer is the viable option before proceeding. Do not reverse engineer a schema where the developers are using Designer to generate forms. In this instance, the developers should be making changes to the ERD, running the Database Design Transformer, and then generating the DDL to update the schema. See steps below to reverse engineer. Therefore, you must make the changes manually.
