discuss at least three major contributions or advantages of Object Oriented Systems Analysis and Design to design a Business System. Use one industry of your choice to discuss your views. For example, you can initiate your discussion as: "Following are advantages I find in creating a cyber-security system to protect patient data in healthcare," or "OOSAD can be used in creating a grocery’s supply-chain management system with the following advantages." These are examples. You can pick any industry or even...
