'ConceptBase 7.0 released' from dbworld mailingCategory :: research |
Dear colleagues!
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
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 ConceptBase!
* 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
