This study uses an applied research methodology with SDLC or System Development Life Cycle design methods and using waterfall paradigm. While the tools that are used in the design UML or Unified Modelling Language, which consists of five design diagrams are: use cases, class diagrams, activity diagrams, state diagrams, and sequence diagrams. Next step is designing process of information display system. Then for the architectural design of information systems that is client-server architecture. The last stage is the evaluation through the design of demonstrating and conducting interviews to companies using the technique through a formal review.

The system that initially runs manually is slowly getting shifted. During the early stage of IT acquisition, managing IT activities relating to operation, programming, and data collection were the major areas of concern. In later stages the focus was on establishing a unit to look after various types of applications over an extended lifecycle, despite change in technology. Simultaneously, emphasis to involve users developed not because of business priorities, but to enable easy use of applications computerized (Misra, 2017). Technology is now a must, especially in an organization.

In addition, the use of a database within a company was more and especially with the network system. The database can be distributed from one computer to another. The number of user flows has increased with the size of the company. Companies need information systems to collect, process and store data and distribute information. Utilization of information technology by the organization or company broadly aims to facilitate the implementation of business processes and improve competitive ability. The process of building software computers and information systems have always been determined by the development methodology different. A software development methodology refers to framework used to plan, manage, and control the process development of information systems (Baxter and Ian, 2013). Through information technology, it is expected that the company's business processes can be implemented more easily, quickly, efficiently and Winduasih, U. and Faldesiani, R.
