Why do we need a mapping load/table anyways ?

Anirban Dutta

Hi

 

i am new to Qlik.

I have mainly developed in MSBI and SAP(BO).

 

Can't see to understand the logic of mapping.

 

What i read it seems it created relation between two tables like a link or associative table.

 

But why do we have to explicitly set up the relation.

If we are loading from a RDBMS isn't the relation should already be defined.

 

Since i am loading a QVD from a data warehouse the data quality is not also a issue.

 

Then why should i need a mapping table.
