SYSTEM DESIGN
    The third of the SDLC is called systems design. During systems design, analyst convert the description of the recommended alternative solution into logical and then physical system specifications. You must design all aspects of the system from input and output screens to reports, databases, and computer processes.
3.4.1 SOFTWARE MODEL ADOPTED
In the development of this system, it was found waterfall model is the most suitable model to be applied and it has the following phases: requirement analysis, design, implementation, testing, integration, operation and maintenance. This model is best suitable for this system because it is possible to gather the requirement before the commencement of the project and it follows a sequential process downward. The model gives room for feedback between every phase in case of error or new information is discovered.
3.4.2 WATERFALL MODEL
The waterfall model is a sequential (non-iterative) design process, used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, production/implementation and maintenance.
    Waterfall uses a systematic approach in the development of software with phases such as phase of system requirement, analysis, basic design, technical design, construction, testing, integration and maintenance, which flow continuously from one stage to another in a downward like a waterfall. Progress “flows” from one stage to the next, much like the waterfall that gives the model its name (melonfire 2006).
