You can generate Interface Definition Language (IDL) files based on Class diagrams. Both CORBA and COM IDL are supported by the IDL export feature. To export a class diagram to IDL, you must first activate IDL export support on the Modules tab of the Explorer (Early Access: IDL Export: IDL Export Support).
Together supports simultaneous round-trip engineering for CORBA IDL. To use this feature you simply create a new project and select CORBA IDL as the programming language in the New Project dialog or New Project Expert. For existing IDL code, you can create a Together project for the existing code.
You can generate Data Definition Language from EJBs, Class diagrams, or Entity Relationship diagrams. DDL output is customized for specific DMBSs. You can see a list of currently supported systems in the Generate DDL dialog (Tools | Generate DDL), second page, in the Server type field.
