What is transaction processing?

you were introduced to the concepts behind transaction processing. But you may still be wondering just what this is. Transaction processing has been around since the mainframe days of computing. You may have heard of, or have even used, products such as CICS, Tuxedo, or TopEnd. These are all examples of transaction processing systems, which provide transaction services to applications that use them. There are a number of attributes that make up transaction processing.In order to discuss transaction processing, we must first agree on a definition of what a transaction is. A transaction is an atomic unit of work that either fails or succeeds. There is no such thing as a partial completion of a transaction. Since a transaction can be made up of many steps, each step in the transaction must succeed for the transaction to be successful. If any one part of the transaction fails, then the entire transaction fails. When a transaction fails, the system needs to return to the state that it was in before the transaction was started. This is known as rollback. When a transaction fails, then the changes that had been made are said to be "rolled back." In effect, this is acting similar to the way the Undo command works in most word processors. When you select undo, the change that you just may have made is reversed. The transaction processing system is responsible for carrying out this undo.

What is ACID test in application in database system?

The ACID model is one of the oldest and most important concepts of database theory. It sets forward four goals that every database management system must strive to achieve: atomicity, consistency, isolation and durability. No database that fails to meet any of these four goals can be considered reliable.Let's take a moment to examine each one of these characteristics in detail: * Atomicity states that database modifications must follow an "all or nothing" rule. Each transaction is said to be "atomic." If one part of the transaction fails, the entire transaction fails. It is critical that the database management system maintain the atomic nature of transactions in spite of any DBMS, operating system or hardware failure. * Consistencystates that only valid data will be written to the database. If, for some reason, a transaction is executed that violates the database's consistency rules, the entire transaction will be rolled back and the database will be restored to a state consistent with those rules. On the other hand, if a transaction successfully executes, it will take the database from one state that is consistent with the rules to another state that is also consistent with the rules. * Isolation requires that multiple transactions occurring at the same time not impact each other's execution. For example, if Joe issues a transaction against a database at the same time that Mary issues a different transaction, both transactions should operate on the database in an isolated manner. The database should either perform Joe's entire transaction before executing Mary's or vice-versa. This prevents Joe's transaction from reading intermediate data produced as a side effect of part of Mary's transaction that will not eventually be committed to the database. Note that the isolation property does not ensure which transaction will execute first, merely that they will not interfere with each other. * Durability ensures that any transaction committed to the database will not be lost. Durability is ensured through the use of database backups and transaction logs that facilitate the restoration of committed transactions in spite of any subsequent software or hardware failures. Take a few minutes to review these characteristics and commit them to memory. If you spend any significant portion of your career working with databases, you'll see them again and again. They provide the basic building blocks of any database transaction model.
