Yep. Sounds like homework to me. I think we're after a simple answer here.
The database could be computer based or paper based.
The database is compiled and utilised by database users in the following way:
As a database user is presented with a problem, they first search the database for the problem.
If they find the problem (i.e. a known problem), they can utilise the solution/s listed against that problem.
If they don't find the problem, they revisit the database after they've found a solution, and create an entry for that problem/solution. In this way, the database is slowly being compiled.
Also, had the problem been found in the database and the listed solution/s didn't work, the database user would normally revisit the database to add their solution to the problem. Again, the database is slowly being compiled.
