JOINS IN HANA

$

Hello Experts,

 

As a newbie, I would like to know which join is better to use if  no referential integrity is maintained, is that an inner join?

Could you please provide the reason why do we use?

 

2) In a calculation view, Is performance gets worse if more number of joins are used and why?

 

3) When Calculated columns are created, at which level do you suggest for the creation?

 

Thanks in Advance,

vinni
