## Global and Local Transactions

Understanding the distinction between global and local transactions is crucial in understanding the Application Server support for transactions. See Transaction Scope.

Both local and global transactions are demarcated using the `javax.transaction.UserTransaction` interface, which the client must use. Local transactions bypass the transaction manager and are faster. For more information, see Naming Environment for J2EE Application Components.
