Title: Chapter 11 Managing Undo Data
Course: RITA MC - ORACLE ADMINISTRATION I > Section: Unit 2 - Database Administration I

Chapter 10 described what happens in memory, and on disk, when you execute INSERT,
UPDATE, or DELETE statements—the manner in which changed data is written to
blocks of table and index segments, and the old version of the data is written out to
blocks of an undo segment. It also covered the theory behind this, summarized as the ACID test,
which every relational database must pass. In this chapter you will see the practicalities of how
undo data is managed.
