DBLX3 Relational Database System
DBLX 3.1 is available! DBLX is a multi-user, client-server relational database. The design goals of DBLX are to produce a very small, very fast database which can be used with standard ANSI sql. DBLX source code is available in C# and Java. DBLX includes the server component, a command-line client, as well as client APIs. DBLX is well-documented so that you can just get the database, drop it on to your favorite system and start using it immediately. Go to the Discussion section to read the latest on DBLX!

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 multiple languages aligning all technologies used by a development team. If you are willing to contribute drop a message.
