Tables are the central objects in a relational database structure,
because they hold your data. But they are not the only objects
that exist in a database. Many other kinds of objects can be
created to make the use and management of the data more efficient
or convenient. They are not discussed in this chapter, but we give
you a list here so that you are aware of what is possible:
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Views
</p></li><li class="listitem"><p>
Functions, procedures, and operators
</p></li><li class="listitem"><p>
Data types and domains
</p></li><li class="listitem"><p>
Triggers and rewrite rules
</p></li></ul></div><p>
Detailed information on
these topics appears in <a class="xref" href="server-programming.html" title="Part V. Server Programming">Part V</a>.
