Database Status questions

"Users in DB" is actually the number of account keys that have been sent out. Some may have been lost, some people may use more than one, some decided to not or not yet participate etc. So the "Users with credit" gives a better overview of the number of really active users. Take into account that the deadline is a week, so in worst case you need to wait a week to get credit, you will see that this number is some days behind the actual activity, though, in contrast to the "Users in DB" which is far ahead.

A Workunit is a Result scheme, a set of parameters that the Results are generated from, a peice of work to do. In BOINC the same piece of work has to be done a number of times (currently three), to make sure it is done right. A Result is sent to your machine, crunches there and is then uploaded and reported to the server, where the validator compares it to the other Results of the same Workunit. When it finds a "canonical" Result, and your Result was considered to be valid, credit is assigned to your account (and your team), the Workunit is considered "over", the canonical Result is kept and the Workunit and its Results will eventually be purged from the database.

I think the VALID and INVALD Results can include DELETED Results.
