SQL Relay is a persistent database connection pooling, proxying and load 
balancing system for Unix and Linux supporting ODBC, Oracle, MySQL, mSQL, 
PostgreSQL, Sybase, MS SQL Server, IBM DB2, Interbase, Lago and SQLite with 
APIs for C, C++, Perl, Perl-DBD, Python, Python-DB, Zope, PHP, Ruby, Ruby-DBD, 
Java and TCL, command line clients, a GUI configuration tool and extensive 
documentation.  The APIs support advanced database operations such as bind 
variables, multi-row fetches, client side result set caching and suspended 
transactions.  It is ideal for speeding up database-driven web-based 
applications, accessing databases from unsupported platforms, migrating between
databases, distributing access to replicated databases and throttling database 
access.
