In the next chapter, we ll look at how SQL can be incorporated into application programs, such as those written in Java, the Microsoft .NET Framework, C, and other programming languages/environments. However, before we do that, you need to understand the concept of database transactions because you will need them in order to properly implement business processes that update the database.

A transaction is a discrete series of actions that must be either completely processed or not processed at all. Some call a transaction a unit of work as a way of further emphasizing its all-or-nothing nature. Transactions have properties that can be easily remembered using the acronym ACID (Atomicity, Consistency, Isolation, Durability): Atomicity A transaction must remain whole. That is, it must completely succeed or completely fail. When it succeeds, all changes that were made by the transaction must be preserved by the system. Should a transaction fail, all changes that were made by it must be completely undone. In database systems, we use the term rollback for the process that backs out any changes made by a failed transaction, and we use the term commit for the process that makes transaction changes permanent. Consistency A transaction should transform the database from one consistent state to another. For example, a transaction that creates an invoice for an order transforms the order from a shipped order to an invoiced order, including all the appropriate database changes. Isolation Each transaction should carry out its work independent of any other transaction that might occur at the same time. Durability Changes made by completed transactions should remain permanent, even after a subsequent shutdown or failure of the database or other critical system component. In object terminology, the term persistence is used for permanently stored data. The concept of permanent here can be confusing, because nothing seems to ever stand still for long in an OLTP (online transaction processing) database. Just keep in mind that permanent means the change will not disappear when the database is shut down or fails it does not mean that the data is in a permanent state that can never be changed again.

Aside from personal computer database systems, most relational DBMSs provide transaction support. This includes provisions in SQL for identifying the beginning and end of each transaction, along with a facility for logging all changes made by transactions so that a rollback may be performed when necessary.
