This 14-video course explores how to execute groups of commands in an all-or-nothing fashion. Learners will examine how locks are used to regulate table access when multiple clients are accessing the database simultaneously. First, you will explore the ACID properties (atomicity, consistency, isolation, and durability) of database management systems. Next, you will learn how transactions, a unit of work which needs to be executed in an all or nothing fashion, work in MySQL. Next, learners you will examine the start transaction keyword, how transactions are defined as committed or rolled back. You will examine implicit commits, operations which create, alter, or drop database entities, such as databases or tables, and how these operations are affected by transaction commits and rollbacks. Learners will observe DDL (data definition language) operations in MySQL. Continue by exploring savepoints, specific checkpoints where the copy of a system state is created, and release savepoints when they are no longer needed. Finally, the course examines the precise semantics of read and write locks in MySQL.
