The need for three level architecture

The aim of the three level architecture is to divide each user's view of the database from the way the database is physically shown.

Support of multiple user views: Every user is able to access the similar data, but have a different customized view of the data. Every user should be able to change the way he or she analysis the data and this change should not affect other users.

Insulation between user programs and data that does not concern them: Users should not directly govern with physical storage details, such as hashing or indexing. The user's interactions with the database have to be independent of storage considerations.
