Business Objects  

SUPERVISOR 

It is with SUPERVISOR that you create the Business Objects repository. You then define users and user groups, as well as assign profiles to them. User profiles include user identification (user name and password), the products and modules they can work with, the universes they can access, and the documents that they can share. You can control user access to Business Objects products, and manage the exchange and distribution of the universes and documents of all users.

Note: SUPERVISOR can run only in client/server mode. Its use requires a connection to a relational database. Any operation you perform with SUPERVISOR is stored in the repository you are working with.

The role and the relationship of the supervisor with respect to other
BUSINESSOBJECTS and INFOVIEW users and resources are depicted in the diagram below:

A Business Objects repository is a set of data structures stored on a database. A repository makes it possible to share the resources necessary for client/server architecture.
