In an attempt to attract developers to the DB2 database, IBM have announced a free version of their flagship database engine, DB2.
The free offering, ‘DB Express-c’ has the same features as the commercial version, but is limited by the hadrward it can be deployed on. The limitations are quite high though – it can only be deployed on a PC with upto a maximum of 2 processors (single or dual core), and 4GB RAM. There are no limitations on the database size.
