<h2 id="rzahyschema">Schema</h2>
|
||
|
|
<p>A schema is a set of rules that governs the way that data can be stored
|
||
|
|
in the directory. The schema defines the type of entries allowed, their attribute
|
||
|
|
structure and the syntax of the attributes.</p>
|
||
|
|
<p>Data is stored in the directory using directory entries. An entry consists
|
||
|
|
of an object class, which is required, and its attributes. Attributes can
|
||
|
|
be either required or optional. The object class specifies the kind of information
|
||
|
|
that the entry describes and defines the set of attributes it contains. Each
|
||
|
|
attribute has one or more associated values. See <a href="rzahywrkdirentries.htm#rzahywrkdirentries">Manage directory entries</a> for
|
||
|
|
additional information about how to manage entries.</p>
