About This Document

This report provides a limited analysis and design comments on the online shopping system. It covers the functional and non-functional requirements, object-oriented approach, API, and more. The report also discusses the advantages and disadvantages of structured vs object-oriented approaches and the importance of UML in object-oriented software development.

PRELIMINARY REPORT: LIMITED ANALYSIS AND COMMENTS ON DESIGN1. IS2: Full Online Shopping System1.1Structure approach to system analysis and design mainly work on processes and on logical structure. After that data is required for the processes. It is basically follow the top to down approach. It has fixed specifications. It uses a list of instructions to get work completed. In this process programs are divided in to various small processes. It has more function dependencies as well as less reusability properties. Structure approach have also less flexibility in nature. Data hiding facilities is also not available in this approach. Whereas in object oriented approach all the works are mainly depend upon data. It divides the whole requirements in to object which carries the methods and data togather. It follows the bottom to top approach. It has properties of data encapsulation as well as polymorphism. It has more reusability and have less function dependencies properties. Here in online shopping system design we are going to use the object oriented approach. Object oriented approach can solve any complex program as well as having data hiding feature. Oops is more famous than structure approach it provide facilities of dynamic binding and multi-threading as well as objects,class etc.1.2The most general approach in SDLC is structure approach which is based upon waterfall model. It follow step by step process to complete the phase. In this we see that work of one phase must completed before moving to another one. Planning, analysis, design and implementation are the main phase of structure approach. It uses set of diagram which repersent functionality of system is mainly termed as DFD. Whereas in object oriented approach have several phases like inception, elaboration, construction and transition. It has no logical process for SDLC . During iterartion it repeated every phases. In this approach we uses different models to repersent the different functionality of the system is also known as UML (unified modeling language). This process followmainly increamental and iterative approach for the development of the system. (Waterfall Method)
