Underground Information System

The following report will give an introduction to WAP, its programming model, the architecture, services and peculiarities in comparison to the World Wide Web. WAP's features are evaluated and especially security, usability, performance and quality-of-service issues are reviewed. Based upon the WAP introduction and its major findings, an analysis and design has been made for a concrete WAP application. This application serves as an information system for transportation systems and allows users to be kept up-to-date on actual maintenance, breakdowns and malfunctions in a transportation network. Functional and non-functional requirements, use-cases, activities, the database scheme, deployment and realization requirements of the proposed project will be discussed. Finally, the report will conclude with an evaluation of the project and a discussion about possible extensions and further work.
