Metabase assures this for you. Metabase goes further, not only it assures
portability of the application acceses to the databases, but is also to
install database schema from a database independent schema definition
format base in XML.
This means that only need to tell which tables, fields, indexes and
sequences in a simple XML file and Metabase manager installs it for
you in any of the supported databases seeminglessly.
The cool part is that if you want to change your database schema (and often
you do), you just need to change the schema definition file and Metabase
manager will update your schema without disturbing any data added to the
database since the database was first installed or was updated for the last
time.

Metabase API is made of simple functions (not objects that you have to
create). Doing what Metabase already does with built-in functions would
not buy you much that would be worthy.
