What you have is a basic "imaging" application. Incidentally, as part of the "indexing" process (Jason mentions it) you probably need to include a capture date and also a brief description of the document that goes into the database. Picture the user who has provided the employee ID seeing a selection list of document images relevant to that employee. That's were that date and brief description are useful.

A good source for such information is the Imaging and Document Solutions magazine, now called Transform magazine.

Look around for what's available.
