I am developing a system using Microsoft Access. A Stock Control Databade with an integrated interface for generating sales invoices and automatically updating stock levels in the database. I am a bit confused as to which Methodology should I use SSADM or OOAD ? Also taking this into consideration what (SDLC) lifecycle model would be best suited for this type of system? And could you hilight som reasons why should I choose one over the other ? All the help I get would be greatly Appreciated ! Thanks in advance!
