CHAPTER 3 : METHODOLOGY 3.0 INTRODUCTION This chapter describes the methods and the methodology that have been use to implement in this thesis. The primary data sources and data collected will describes how the methods being used and how they were structured. This chapter also explains about how the data that found are being coded and theoretical understanding approaches which in terms of their methodology. This chapter will help and provides an idea towards the objective of this thesis by discussing the research began how it proceeded and how the data were being coded. There will also describes the major stages that must be taken and the approach to that problem occur that will be reported in this thesis. 3.1 SYSTEM DEVELOPMENT System development is a standard process or flow of the methodology to structure all steps necessary to analyze, design, implement and test the system. It is important when we want to develop the system. System Development Life Cycle(SDLC) can be known as the process of creating or altering systems, and the models and methodologies that people use to develop systems. SDLC is a system approach to problem solving and is made up of several phases, each comprised of multiple steps. [9] There are various SDLC methodologies have been developed to guide the processes involved. In general, an SDLC methodology follows the following steps: 1. The existing system is evaluated. Deficiencies are identified. This can be done by interviewing users of the system and consulting with support personnel.

2. The new system requirements are defined. In particular, the deficiencies in the existing system must be addressed with specific proposals for improvement. 3. The proposed system is designed. Plans are laid out concerning the physical construction, hardware, operating systems, programming, communications and security issues. 4. The new system is developed. The new components and programs must be obtained and installed. Users of the system must be trained in its use, and all aspects of performance must be tested. If necessary, adjustments must be made at this stage. 5. The system is put into use. This can be done in various ways. The new system can phased in, according to application or location, and the old system gradually replaced.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
