/**
 * TDbTransaction class.
 *
 * TDbTransaction represents a DB transaction.
 * It is usually created by calling {@link TDbConnection::beginTransaction}.
 *
 * The following code is a common scenario of using transactions:
 * <code>
 * try
 * {
 *    $transaction=$connection->beginTransaction();
 *    $connection->createCommand($sql1)->execute();
 *    $connection->createCommand($sql2)->execute();
 *    //.... other SQL executions
 *    $transaction->commit();
 * }
 * catch(Exception $e)
 * {
 *    $transaction->rollBack();
 * }
 * </code>
