The project can solve any business problem that requires storing and manipulating data in multiple tables (SQL server database will work...please include the database in bin and use relative reference).
The technical details are:
1. Should have 3 different tiers (UI, Business, and DataTier).
No business logic or DB in UI
No DB code in Business tier (use colllections of objects send information)
2. Should use either remoting or web services to accomplish one of the tasks.
3. At least 3 tables with proper relationships (referntial integrity etc.)
