Abstract
The vertical decomposition, explained in Chapter 4, is a useful tool for reducing redundancy in the database and for improving the speed of query evaluation and updating. However, in the real world the constraints on which the decomposition relies may not be easy to find, and exceptions may appear after a database system is in use for some period of time.
