SQL Relay is a set of daemons and clients with C, C++, Perl, Python, Zope and 
PHP APIs for maintaining persistent connections to Oracle, MySQL, mSQL, 
PostgreSQL, SQLite, Lago or Sybase (via FreeTDS) databases and executing 
queries through those connections. It is especially useful for migrating 
between databases, accessing replicated databases and speeding up 
database-driven web-based applications.
