You can generate the internal schema for a selected target DBMS by clicking
Database | Generate from the Database menu. Generation gives you the option
of generating the DDL script rather than having the tool build the tables
for you. It is usually best to first generate the DDL script, which you can
later execute within your chosen DBMS. Follow the steps in the generate
wizard, choose your driver (for example, Microsoft® SQL ServerT 2000), enter
a database name (for example, mydb), accept defaults for the next screen,
choose Yes to view the generated DDL script, then save the DDL script as a
text file.
