Constantly growing data volumes and accelerating update speeds are fundamentally changing the role of data warehousing in modern business. Data warehousing is increasingly used not only for strategic, but for operative decision making as well. More data, coming in faster and requiring immediate conversion into decisions means that organizations are confronting the need for right-time (active) data warehousing. In parallel, great advances, both in wireless networks and respective mobile devices

Mobile devices become smaller, cheaper and more powerful, being able to run more sophisticated applications and network services. With ubiquitous data access already being success critical, integrating mobile devices in existing infrastructure is a fundamental requirement. The research field of mobile online analytical processing (mOLAP) brings the two aforementioned research and application areas together. The term mOLAP encompasses all necessary technologies for mobile information systems that enable multidimensional data access to users carrying a mobile device. This thesis presents FCLOS, a complete client-server architecture explicitly designed for mOLAP. FCLOS exploits derivability between multidimensional data cubes in conjunction with wireless broadcast in order to become a query efficient, self adaptive and scalable mOLAP information system.
