International Journal of Web Applications Shilpi Taneja, Anita Goel 7 2 2015 http://www.dline.info/ijwa/fulltext/v7n2/v7n2_2.pdf This paper proposes a mobile app architecture that reuses the resources of the existing student information system of educational institutions. The educational institutions have an existing website that interacts with a data store to disseminate information to its stakeholders. The data store and the web resources have been reused for the mobile app. Web services are developed to fetch information from the data store. The data fetched via web services is presented via appropriate screens. Design of a complete new application requires a lot of effort during development and testing, to come up with a stable product. Reuse of existing infrastructure and software simplifies the task by focusing mainly on the new features and saves cost, time and effort. A prototype developed for University of Delhi using the proposed architecture is discussed in detail. The architecture enables delivery of individualized information to students on their mobile devices which is accessible anywhere and anytime. This keeps students informed and satisfied. The architecture can be replicated to design mobile app for any organization having a data store.
