[Kuk]

Aqui os dejo el enlace oficial de IBM. Es una BBDD totalmente gratuita!!! No la he probado pero debe ser bastante buena:

Segun este enlace, practicamente no hay limitaciones. Y lo que es mas importante es que no hay limitaciones de tamaño de la BBDD:

Para trabajar con la BBDD mas facilmente, se necesita IBM Data Studio.

Limitaciones:

IBM DB2 Express-C does not limit the amount of data that can be stored in a database, nor does the database engine limit the number of concurrent user connections.
IBM offers 64-bit native versions of DB2 Express-C for all supported platforms, but 32-bit versions are still available for some environments.
Remote applications can connect to DB2 Express-C over TCP/IP V4, TCP/IP V6, or named pipes. The DB2 Express-C database engine is limited to use up to 16GB RAM (increase from 4GB with v10.5) and two CPU cores, but it can be installed and used on machines of any size, with the remaining memory and CPU available for use by the O/S and other applications.

The DB2 Express-C feature set is very similar to DB2 Express edition (a paid product), but the main difference is that Express-C has lower CPU and memory limits. It has the following extra features enabled:

Backup compression
Homogeneous federation - only DB2, Informix Data Server and Oracle targets are supported
Homogeneous SQL replication
Net Search Extender
XML storage
Spatial extender

¿Alguien ha probado este producto?

Yo no, en la empresa se apostó por SQL Server y cambiar ahora no sería factible.

Supongo que será buena y que con tiempo, se podían hacer interesantes pruebas.
