Database Transactions: Part 1

Описание к видео Database Transactions: Part 1

In this video we introduce the concept of a database transaction. A transaction is a set of steps within SQL's Data Manipulation Language (DML) that are to be seen as a unit. They should be taken as all or nothing and move the database from consistent state to consistent state. If all of the steps succeed, then we can COMMIT the transaction; if not then we need to ROLL BACK the any steps of the aborted transaction. We mention the ACID test that says that database transactions should be Atomic, Consistent, Isolated, and Durable.
