Database programming method

I'm talking about a method of writing a database application. You can use this method surely, because this is experience based way of programming.

The steps are:
1. Collect your User Requirement Definitions.
2. Now draw your Database Diagram. In database diagram must have all required outputs (reports).
3. You may need to draw Data Flow Diagram to make the system clear.
4. Create all forms that register data. On all command actions call an empty stored procedure that will be created later.
5. Create all program reports by using user requirement defns. Any report must be bound to exactly one database table according to Step 2.
After this 5 ways, you have an application that gets inputs, gives reports, but no processing involved. You can give it to customer to try how to work.
6. Now start writing stored procedures for main processing. It's easy. You have already named stored procedures and defined what to do in it.

My teacher said that:
Success of developing application program is based on systematic method. That's why there are many methods such as traditional system analysis, UML, RUP and so on. But if you have your way of developing programs, that is better than these standards.

I agreed it. Because i created it, suits me and my environment perfectly, no more work, can be changed freely ...
