100% concur with Brenda, there's no harm in querying the Content Store though you obviously do need to be careful not creating and blocks or deadlocks. Always best to query it during the least amount of activity or better yet, do it in your dev environment. To protect oneself from oneself, create (or have your DBA do it) a user that has select-only permissions in the database. Again, using a Dev environment is always the best way to go.
And as others have said, IBM has never really published the schema of the content store because it's always subject to change and just one more set of documentation for them to maintain.

Anyone with permissions can query the Content Store. I do it all the time. Querying any database data does not alter/change/update/modify/delete any data. No harm will be done.

Hello,
You won't find any information about the schema of the Content Store. It is designed to store metadata to be read and updated by the IBM Cognos service principal only. I think you will find some instances where well meaning admins have destroyed their instance. For this reason you should not be connecting to this database and is the reason there is no published schema.
In addition, each fix pack and update will potentially alter tables.
https://www.ibm.com/support/pages/faq-security-concerns-regarding-credentials-stored-content-store "Content Store is considered a black box environment, one MUST NOT access the tables with anything but IBM Cognos BI functionality."
Not sure what you are trying to achieve, but you should investigate extracting information with report schedules, audit reports, audit extension, or SDK. This will ensure security of your database and stability of the Cognos application.

Hi all,
I am looking for documentation regarding Cognos Content store tables descriptions for v11.0 and v11.1. So far my search turned up only old Cognos 8 descriptions, but they don't seem to match.
Thanks in advance.
