There are many kinds of entities that we wish to identify, describe, manage, and share among multiple business functions and application systems at an institution: people, groups, departments, roles, courses, budgets, computers, services, etc. Proper management of information about these entities allows this information to be well-maintained and easily shared among all systems.
