Oracle Transaction Management
A transaction is a logical unit of work consisting of one or more SQL statements. Transactions may encompass all of your program or just a part of it. A transaction may perform one operation or an entire series of operations on the database objects. You can execute transactions interactively or as part of a program. Transactions are begun implicitly whenever data is read or written, and they are ended by the commit or rollback statement.
