Advantages of Using Virtual DIT Views
Your deployment decisions become easier with virtual DIT views:
•
Views facilitate use of flat namespace for entries because virtual DIT views
provide navigational and managerial support similar to the ones provided by
traditional hierarchies.
In addition, whenever there is a change to the DIT, the entries will never need
to be moved; only the virtual DIT view hierarchies will change. Because these
hierarchies contain no real entries, they are simple and quick to modify.
•
Oversights during deployment planning are less catastrophic with virtual DIT
views. If the hierarchy is not quite right, it can be changed easily and quickly
without disrupting the service.
•
View hierarchies may be completely revised in minutes and the results
instantly realized, significantly reducing the cost of directory maintenance.
Changes to a virtual DIT hierarchy are instantly realized. When an
organizational change occurs, a new virtual DIT view can be created quickly.
The new virtual DIT view can exist at the same time as the old virtual DIT
view, thereby facilitating a more gradual changeover for the entries themselves
and for the applications that operate on them. Because an organizational
change in the directory isn't an all-or-nothing operation, it may be performed
over a period of time and without service disruption.
•
Using multiple virtual DIT views for navigation and management allows for
more flexible use of the directory.
With the functionality provided by virtual DIT views, an organization can use
both the old and new ways to organize directory data without any requirement
to place entries at certain points in the DIT.
•
Virtual DIT view hierarchies can be created as a kind of ready-made query to
facilitate retrieval of commonly-required information.
•
Views promote flexibility in working practices and reduce the requirement that
directory users create complex search filters filled with attribute names and
values that they would otherwise have no need to know.
The flexibility of having more than one way to view and query directory
information allows end users and applications to find what they need
intuitively through hierarchical navigation.
