public interface IJdbcConnectionProvider

An interface for generically providing JDBC connections. The intention of this interface is to encapsulate all database specific issues of constructing a URL or the driver name.

Clients of IJdbcConnectionProvider simply call getConnection(String, String, String, String, String, String...) in order to get a valid driver URL constructed and passed to DriverManager.
