do not know to use a card catalogue. Now, students that will search for books will just type the title or the author or just a topic name then click the “Search” buttons. It will then display every book that matches your search topic including the books’ author, title, and its location.CHAPTER 3METHODOLOGY3.1 Method Used in Developing the Software ProductGiven only with limited time and resources, the researchers adopted the prototyping paradigm. The prototyping model allows all or the system to be constructed quickly so that the desired characteristics of the system can be decided or clarified early on. Also, the requirements or design are repeatedly investigated to ensure that the developer, user, and the customer have a common understanding both of what is needed and what is proposed.The figure below illustrates a prototyping dataflow. One or more of the loops for prototyping requirements, design or the system may be eliminated, depending on the goals of the prototyping. However, at each step, a prototype can be used to explore any aspects of the system that may need modifications. Below is the prototype dataflow.SYSTEM REQUIREMENTS DELIVERED(Sometimes informal or incomplete) SYSTEMProcesses, so that requirement can be modified as the analysts examine available options. In other cases, the customer knows what is needed or wanted, but the analysts are not certain whether the requirements can be met. Here, the analysts may determine whether the customer’s problem has a feasible solution.The Prototyping ProcessProblem with building information system: (1)the system development life cycle takes too long and (2) the right system is rarely developed the first time. It advocates building a simple system through trial and error and ref...
