I guess I am too suspicious too tell, but I can tell you a few advantages
or features of Metabase that other DB abstraction layers do not have or are
now following the design:
- Database schema definition in XML that Metabase manager installs or updates in
any of the supported databases. Good for migrations just in case you
need them in the future.
- Large set of base datatypes that Metabase assures that will work portably
across databases: integer, text, date, time, timestamp, floating point,
fixed point and boolean.
- Selecting just a range of rows of a SELECT query, like MySQL LIMIT, but
works with ALL supported databases.
- Auto-incremented integer sequences.
- Transaction support for databases that can handle them.
- etc...

Look in the documentation directory of the list of files. There is a
metabase.html which the whole reference manual and the tutorial.html .
