Need to finish a class project with very quick turn around time. Need the code by 8th of December. Things should be simple and take care of following criteria: **Final Project** The final 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). 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.) This project do not have to be complicated ... a library book check out system or similar will work. Just simple business processs.
