NIS and NIS+ share little more than their name and a common goal.
|
|
NIS+ is structured in an entirely different way. Instead of a flat
|
|
name space with disjoint NIS domains, it uses a hierarchical name space
|
|
similar to that of DNS. Instead of maps, so called <em>tables</em> are
|
|
used that are made up of rows and columns, where each row represents an
|
|
object in the NIS+ database, while the columns cover those properties
|
|
of the objects that NIS+ knows and cares about. Each table for a
|
|
given NIS+ domain comprises those of its parent domains. In addition,
|
|
an entry in a table may contain a link to another table. These features
|
|
make it possible to structure information in many ways.
|
|
<P>
|
|
Traditional NIS has an RPC version number of-2, while NIS+ is
|
|
version-3.
|
|
<P>
|
|
NIS+ does not seem to be very widely used yet, and I don't really
|
|
know that much about it. (Well, almost nothing). For this reason, we
|
|
will not deal with it here. If you are interested in learning more about
|
|
it, please refer to Sun's NIS+ administration manual
|
|
([<A HREF="#nisplus"></A>]).
