6. Step 2: Design Access layer classes
• An OR model (object – relational) mode is
drawn here.

And so on , all relations are identified

7. Step 3: Design View Layer Classes.
• We develop GUIs here. It is just a working
model (prototype).for Example,

8. Step 4: Iterate and refine the whole
design.
• Repeat steps (i) through (iii) again, if desired.
