Our global sales managers want to view the tickets based on their sales regions such as Europe, MEA etc. I've thought that creating a new field on the account layout for the regions was the solution to create those views but later on found out that each functional section (Tickets, Contacts, Accounts etc) has its own data table setup and they aren't linked together.

You normally market your products as having connected data structures such as in Creator. Take a look in the attached video file from the "Feature" page of Zoho Creator.

We should be able to filter out tickets also based on the other connected data tables (if they are really connected). Could you please explain if my comments are correct or if there are some other reasons for the current infrastructure.
