de.mhus.lib.sql.DbConnection
This class is a proxy for DbProvider and it is the public interface for it. It will automatic free the provider in the pool if the connection is no more needed. @author mikehummel

DBConnection manages connections to databases.
It implements two Design-Patterns:
1. Singleton: An instance of DBConnection is created for every thread. This instance can be fetched with getInstance().
2. Facade: The complexity of creating and managing a connection is capsuled.
org.apache.turbine.util.db.pool.DBConnection
This class wraps the JDBC Connection class, providing built-in exception logging to stderr and a timestamp which indicates how old the Connection is. DBConnection's timestamp is used by the ConnectionPool to expire connections when they get too old. Do not use this class as a shared resource (it is not thread-safe). @author Frank Y.
