If cardinalities are not resolved in Business Objects Universe

Cardinaliries in Business Objects :

I would say it explain relationship between two tables. How are they joined ?

Data in real world is distributed in multiple tables and in order to create report for anyone we need to join those tables.

There are multiple ways you can join the tables as shown below.

1. One-to-One (1-1)
2. One-to-Many(1-N)
3. Many-to-one(N-1)
4. Many-to-many (N-N)

If Cardinalities are not specified in Business Objects Universe Design Tools, we can get more then we requested.Also, it would be difficult to detect Loops & Traps (Chasam & Fan).
