/* The general design is to use one relational table per objectclass. This is
|
|
* complicated by objectclass inheritance and auxiliary classes though.
|
|
*
|
|
* Attributes must only occur in a single table. For objectclasses that inherit
|
|
* from other classes, attributes defined in the superior class are only stored
|
|
* in the superior class' table. When multiple unrelated classes define the same
|
|
* attributes, an attributeSet should be defined instead, containing all of the
|
|
* common attributes.
|
|
*
|
|
* The no_set table lists which other attributeSets apply to the current
|
|
* objectClass. The no_attrs table lists all of the non-inherited attributes of
|
|
* the class, including those residing in an attributeSet.
|
|
*
|
|
* Usually the table is named identically to the objectClass, but it can also
|
|
* be explicitly named something else if needed.
