I finally reached Beta 5 with my pet project. It now supports manufacturing of code for DB/2 LUW 10.1, SQL Server 2012, MySQL 5.5, Oracle 11gR2, Sybase ASE 15.7, and PostgreSQL 9.1.
I've finally achieved what I set out to do 15 years ago -- provide a multi/cross database coding tool that automates the mapping from an abstract business model to the specifics of the database while using all of the available performance tuning options of the database. This is far more challenging and complex than something like EJB3, which just generates dynamic SQL, not stored procedures and prepared statements.
Next up will be using the tool to write an application. I'm thinking of doing something simple and straight forward, like the core of an accounting system with general ledger, accounts, subledgering, and so on. During that development I may well add in the security support I've been planning all these years, but maybe not. Time will tell.
Regardless, I'm just peaking to have finally achieved this long outstanding milestone.
