Check Integrity serves the following purposes:

It detects any inconsistencies in the objects, joins, conditions, and cardinalities of your universe.

It detects whether there are any loops in the joins.

It determines whether changes were made to the database to which the universe is connected.

Question: 45

How do you design a universe?

The design method consists of two major phases.

During the first phase, you create the underlying database structure of your universe. This structure includes the tables and columns of a database and the joins by which they are linked. You may need to resolve loops which occur in the joins using aliases or contexts. You can conclude this phase by testing the integrity of the overall structure.

During the second phase, you can proceed to enhance the components of your universe. You can also prepare certain objects for multidimensional analysis. As with the first phase, you should test the integrity of your universe structure. Finally, you can distribute your universes to users by exporting them to the repository or via your file system.
