Chapter 9. Advanced Transaction Control

In this chapter, I discuss the various problems that relational database systems must solve when dealing with many users running different transactions involving the same tables at the same time. I describe how these problems are solved by modern database systems, and provide an example showing how you can alter the default transaction isolation, the degree to which the results of one transaction interfere with other transactions.
