Model driven code generation can improve coding standards, speed, quality of development and reduce your costs. From my experience generating code from XML using XSLT is one of the best and fastest solutions.
This is just the base of the framework presenting the idea, any code template can be implemented upon request.
Some sample generators are present for SQL / PLSQL / C# / AnsiC / Java
The main target is to generate DTO/BDO/POJO objects based on the database definitions in...
