Muhammadiyah University of Magelang (UM MAGELANG) has integrated academic information systems in terms of both data and applications. This system has been constructed since 6 years ago and has been used by the service level to the policy level. However, until today, there is no data can be presented in an appropriate format for the decision maker, since the data are separated functionally. In addition, reporting data is not easily used by decision makers because it does not apply the concept of the data warehouse. So that the information can be used by decision makers, the data warehouse must be constructed using appropriate methods. In this paper Kimball methodology is chosen because the design starts from user needs. The methodology causes the system to be able to present complete and appropriate data presentation as well as the user wants. UM MAGELANG Academic Executive Information System (EIS) has been successfully constructed using the data warehouse. As a result, the system is able to present the integrated data and is able to demonstrate factual data from a variety of dimensions as required by decision makers. By using the EIS, the decision maker can trace the problem source that happened in their education system.
