ConceptBase 7.0 released!

We are happy to announce that the new release 7.0 of ConceptBase, a deductive object manager for conceptual modeling and meta modeling, can now be downloaded from http://www-i5.informatik.rwth-aachen.de/CBdoc/

An introduction to the system is available at http://conceptbase.cc

ConceptBase is developed at Aachen University of Technology (RWTH) and Tilburg University. It is free of charge for non-commercial use.

Highlights of ConceptBase 7.0

• Supports more platforms: Besides Linux, Solaris, and Windows, we now also support Mac OS-X for PowerPC and Linux64 for x64. The support for x64 CPUs has virtually removed the 4GB limit for databases.
• Much faster for most operations: Query processing is between 30% and 2500% faster. For example, the computation of the transitive closure of a graph with 1400 nodes took 300 seconds with ConceptBase 6.1. It now just takes a few seconds. Simple queries to smaller databases enjoy a more moderate speed-up.
• More expressive: In particular, the active rule component is now fully integrated with the integrity checker and its computational model has been changed. You now can easily define the dynamic semantics of petri nets as a meta model in Telos!
• Small and robust: While ConceptBase is typically installed on hard disks, you can also install it on a memory stick or CD and start it from there without any further installation.

ConceptBase 7.0 is capable to manage large models with literally hundreds of thousands of concepts. Earlier versions already greatly supported the meta modeling of conceptual modeling languages. With the new release, you can also start to define semantics of dynamic modeling languages and use the configurable graph editor to visualize models and their use.

A detailed list of the changes since version 6.1 can be found in the release notes.
