Leadership Development Database Setup Ideas?

We as Administrative Elders have set a goal to develop future leaders in our congregation.  We're currently finding out who has served in leadership roles in the past (leadership being elder, deacon, small group leader, other team/committee leader, etc, etc) and we're going to ask current ministry leaders and staff to suggest names of potential leaders.  Then we'll plug all this into a database of some sort, and then we'll provide leadership opportunities for this group in the future.  A couple of benefits of this are knowing what gifts/strengths are in our congregation, and when we have a new deacon or elder on council, s/he is not starting from square one.
 
We're wondering if anyone else has set up anything like this?  If so, what did you track in your database?  What sort of leadership opportunities did you provide?  Any other guidance you can give us?
