Resumo:
The emergence and constantly growing popularity of portable devices such as notebooks,
laptops and personal digital assistants (PDAs), and the advances in the technology of wireless communication networking, have motivated research in a new class of applications called mobile or nomadic, which permit users to have access to information from anywhere at any time. Among these new applications we focus on Mobile Data Warehouse (MDW). To construct MDW systems means to transpose innumerable challenges, such as: availability in low capacity networks, function on small sized mobile platforms, whilst at the same time guaranteeing high performance in OLAP queries on DW. As an emerging technology there are various problems still not satisfactorily resolved, or unconcluded. This dissertation proposes an MDW management software, that has as its main objectives: the simultaneous updating of various MDWs without burdening the data communication network, the allocation of diverse MDW maintenance tasks outside of the mobile platforms, and the imperative of the efficiency of updating algorithms.
