DatabaseConnector is a handy PHP wrapper class to allow easy access to database connections to different database types without changing of usage, queries etc..

The class uses the PHP PDO functionality and is able to connect to each database type, that's driver is installed/activated in the PHP configuration and also to use transactions and prepared statements.
