I believe that DBMan can do all that you require with the use of some mods written for the script.
In the resource center you will find a listing of the various mods written for the script. Also there is an excellent DBMan tutorial at http://www.jpdeni.com/dbman
There are also some threads available by searching the forums which would contain information from others who have created project management type databases.
To see the many possibilites you may want to check out the FAQ noted below which contains over 900 thread references. You will get many ideas and options along with learning some tips and tricks of using DBMan.
Hope this helps
