A Database System for Metamodeling and Method Engineering
ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos.
ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level...
A relational database management system, based on the principles laid down in the book "Databases, Types, and The Relational Model: The Third Manifesto" by C. J. Date and Hugh Darwen.
Free to join for developers who support the Free Software Foundation cause. This is my research project from 2003, which I recently updated with acceleration- and console changes (Surround Sound, Doppler Effects, Device Updates, Physics) in a long weekend but project should be considered abandoned. Additionally, the Performer libraries have been abandoned by Silicon Graphics. Minor setup- and make reconfiguration bugs, no changes planned. The Command Centre is a Simulation Programming...
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...
