Dear All, Interesting discussion, so here are my 2 cents.
First a disclaimer, I am no database expert at all, but have experimented with sqlalchemy, sqlite etc. In addition, I recently experimented with CouchDB which is a NoSQL database. I don't agree with Jelle that NoSql db's are really built for web 2.0 like applications. As an example, CouchDb is used by CERN to distribute the data obtained from their large hydron collidor (http://www.readwriteweb.com/enterprise/2010/08/lhc-couchdb.php). In my work, I used CouchDB to distribute live test data obtained from physical tests. In particular, I used the replication feature of CouchDB to synchronize a test database at our internal network (directly hooked up to several data acquisition systems) and a database in our DMZ used for live post-processing and monitoring of the test. Databases like CouchDB can in my opinion be really usefull for storing CAE data in collaborative environments. For example, CouchDB is very document centric. In terms of CAE like applications I can imagine that raw topological data is stored as binary data in the document, while meta-data or OCC XDE data is stored in document attributes. Searching metadata/XDE info would be very fast and efficient and could easily be distributed over several databases. I will try to write a testcase in the next few weeks and post it here.
