Currently I am in the development of my final year project which involved in .net programming and WAP. I have two system which is one I develop using visual basic.net for end user in PC, and the other system is for WAP mobile phone user. I transfer the data between the PC to WAP using web services. What I want to ask is, what type of methodology do I have to use to design this system. I am developing the system using structured programming not object oriented programming.
