ER-Designer future DBMS support
ER-Designer is designed to support multiple DBMS system. The DDL generation is done with QScript (ECMA script) that has connections (through the Qt signal/slot system) to the meta-model.
It is just a matter of time to generate the DDL for more DBMS system. After we get the MySql RE working, the next DBMS will be PostgreSQL, then onto the big Oracle, and MS SQL Server.
