The dbmstools module exists mainly for developers
who need to support applications on more than one
database management system (DBMS). It's intended
to allow all the database information (schema and
base data) to be kept in one single place, and to
have DBMS-specific scripts (for creating and
populating the database schema, and upgrading from
one version to the next) generated from that data.
It can generate schema documentation for any DBMS
(including diagrams), and can export data from a
database in several formats. It also has wrappers
for several tools so that they can be run from
within Apache Ant. It supports PostgreSQL 7 and 8,
Oracle, SQL Server, MySQL, and Hypersonic (limited
support).
