Perl module to manipulate schemas independently of databases

 DBIx::DBSchema objects are collections of DBIx::DBSchema::Table objects and
 represent a database schema.
 .
 This module implements an OO-interface to database schemas. Using this
 module, 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 from a different process. Most importantly, DBIx::DBSchema
 can write SQL CREATE statements for different databases from a single source.
 .
 Currently supported databases are MySQL, PostgreSQL, Oracle, Sybase and SQLite.
 DBIx::DBSchema will attempt to use generic SQL syntax for other databases.
 Assistance adding support for other databases is welcomed. See the
 DBIx::DBSchema::DBD manpage, "Driver Writer's Guide and Base Class".
