Hi

I am planning to make a program (Accounting and Budgeting, Billing, Inventory, People and Organizations, ......)
so I need some information about many subjects:

  1. What is the structure of the database should look?
  2. Is there any (Controls, Components, Programs, ....) you suggest that will help me while I am developing this type of Applications?
  3. Is there any thing else should I take care of it before starting this mission?


Please help me!
