OpenDBX is an extremely lightweight but extensible C library for 
accessing databases with a single API. It provides a clean and simple
interface across all supported databases that leads to an elegant
code design automatically. Currently MySQL, PostgreSQL and SQLite are
supported and backends for more native database APIs can be written
easily. If you want your application to support different databases
with little effort, this is definitively the right thing for you!
