Data Views

Typically, a database has several users and each of them, depending on access rights and desire, needs an individual view of the data (content and form). Such a data view can consist of a subset of the stored data or from the stored data derived data (not explicitely stored).

A university manages the data about students. Beside matriculation number, name, address, etc. other information, for example in which course the student is registered, if he needs to do a resit, and so on is managed as well.
This extensive database is used by several people all with different needs and rights.

Please click on the four buttons below to see the different data views for different users of this database.

Different Data Views

The database administrator has a view on the whole database while other users in this example have only a restricted view on the database. The administrator, for example, does not need information about names and matriculation numbers in case they want to create an anonymous statistic about the resits. In the student lists there should not be any sensitive data about the resits or similar. However, the lecturer of a class needs the detailed information about the students in this class including resits and so on.
