Abstract
Communitative English is the first non-language institution in the city of Pontianak, which was founded in 1975. Communitative English has a variety of classes starting from the beginner class, classes specifically for employees used for the TOEFL class. Communitative English has not implemented web technology in the process of information dissemination and registration making it felt inefficient. The research that I use and in this study is a case study using Research and Development methods. Data collection techniques used were interviews, observation and literature studies. In addition, primary data is also used from interviews and observations and secondary data obtained from data and journals from previous research. The design method used is Rapid Application Development (RAD) with Unified Modeling Language (UML) system modeling tools obtained based on data from using case diagrams, activity diagrams, sequence diagrams and class diagrams. The programming language used is PHP and MySQL as a database. The results of this study will produce a data security system using xml encryption that can be used to manage selective communicative English data distributed online.
