4 tipes of catlogs we have in cognos

1.Personal Catlog: Only one user(Creator) can create/modify a catlog & report.

2.Shared Catlog: Only one user(Creator) can create/modify a catlog. But any body can create their own reports using this catlog.

3.Destributed Catlog: Here any body can change their own "personal destributed catlogs, they can create their own reports.

But no one can change the master distributed catlog.if u make any changes in master destributed catlog the changes will be effected  to Personal destributed catlogs.

4.Secured catlog:No one can change the catlog & Report it is fully secured

Here better We can choose the Distributed Catlog.
