you can create a database schema with an OO Perl interface. You can read the
schema from an existing database. You can save the schema to disk and restore
it in a different process. You can write SQL CREATE statements statements for
-different databases from a single source. In recent versions, you can
-transform one schema to another, adding any necessary new columns, tables,
-indices and foreign keys.

Currently supported databases are MySQL, PostgreSQL and SQLite. Sybase and
