Define catalog in Cognos and write its various types?

A catalog is a file which contains information such as folders, columns, conditions, etc. on the database tables. The highlighted point here is that it doesn’t contain any data instead it contains metadata definitions and table structures. It has mainly four types:

• Personal Catalog: It is a type of catalog in which only one user can create or modify a catalog or report.
• Shared Catalog: In this, one user (creator) can create the catalog but other users can also create their own reports with the use of this catalog.
• Distributed Catalog: In this, anyone can change or modify their own created distributed catalogs and can also make their own reports.’
• Secured Catalog: In this type of catalog, no one can modify the reports or catalogs. They are fully secured.
