Increasingly divers are undertaking training from more than one agency so Dive Data 2000 has been updated to respect this variety. For example an individual may learn to dive on holiday by taking a PADI Open Water course. On return he or she may join a local BSAC branch, but with experience may want to do a Trimix or rebreather course with one of the technical agencies such as IANTD. Perhaps he buys a boat and wants to improve navigational or boat-handling skills with a RYA certification, or wants to improve First Aid skills with a course from DAN or the Red Cross.

At the branch level, many dive clubs are adopting an "ecumenical" approach where they will accept members trained with any recognised diving organisation rather than forcing them to cross over to a particular certifying agency. Dive Data 2000 supports this approach by maintaining a portfolio of subscriptions for each diver in the branch. A diver can be a member of one, many or even no certifying agencies and each month the membership secretary is provided with details of any subscriptions that are due.

The only thing that isn't stored is extensive financial information. Each branch is likely to run it's finances differently, and in many cases it would be inconvenient for the treasurer and records officer to keep their records on the same PC. A spreadsheet or a simple accountancy program, such as Quicken will make a much better job of storing financial data. Dive Data 2000 does provide information about subscriptions received from members each month, intended to provide the Membership Secretary with a listing which can easily be forwarded to the treasurer.
