2 5.14. Other Database Objects #
4 Tables are the central objects in a relational database structure,
5 because they hold your data. But they are not the only objects that
6 exist in a database. Many other kinds of objects can be created to make
7 the use and management of the data more efficient or convenient. They
8 are not discussed in this chapter, but we give you a list here so that
9 you are aware of what is possible:
11 * Functions, procedures, and operators
12 * Data types and domains
13 * Triggers and rewrite rules
15 Detailed information on these topics appears in Part V.
