Hello,

There are no difficulties building the universe as long as you have a clear understand of database concept. Once you have a good knowledge of database structure than you can use our Information design tool (IDT) or Universe design tool (UDT)

to extract, define, and manipulate metadata from relational and OLAP sources. Normally, you need to be able to understand the SQL expression very well. You have to be able to understand how the data security works for each team and individual. You need to know how join woks, Alias, Loops, Contexts, Index, Aggregated Awareness, etc. As well as middleware concept (JDBC, ODBC, etc). You need to be able to understand the difference between OLAP (Cube) and relational sources. Normally, DBA can fit in to build a good universe. My strong recommendation is for you to take as many training\practice as possible before start building any official universe. If it’s possible work with someone who has built universe before. There is also many YouTube you can use.

Thanks,

Sonet

OLAP universe is bit straightforward.Classes and objects will create automatically in OLAP universe.

You can start looking on below points for relation universes. If you will search on google you will get multiple blogs.

1)use of context vs alias and when?

2) how to resolve loops?

3) how to set aggregated awareness.?

4) How to create derived /views and pros/cons ?

5) explore different function available in universe and how to use them in creating custom objects?

6) row level security setup and benfit.
