Generate database from ERD. Reconstruct structure of a legacy system. Or jump start for a new one.
Design database in ERD, and generate it. The database generation tool validates your database design and produces the database initialization scripts required for database construction.
You can now specify the the function to use in creating a database index, under the Index specification window of an entity.
PostgreSQL users can now specify an entity as unlogged through its specification window. Make sure PostgreSQL has been selected under the Database Configuration window (Tools > DB > Database Configuration...)
Revise database design, and patch the changes to database. The database patch tool analyzes your database and produces the update scripts required to patch changes. Sophisticated checking would be applied to ensure patching will work whilst keeping existing data intact.
Working with legacy database becomes even more challenging when the documentation has been lost in time. Make it available again by reverse-engineering the ERDs. Visually study the table structures and their relationships.
