RESUMO

This work presents an architecture for using Data Warehouses in mobile computers and describes the architecture components (data and processes) that allow the data synchronism based on metadata and restricted to the scope of access for each user. The data structures and the processes composing the architecture are reduced to already known and solved problems, justifying its feasibility. Besides, this work also provides the guidelines to evaluate the complexity and impact caused by changes of schema in the central Data Warehouse that must be reflected in the data marts located in the mobile platforms. The analysis of the complexity and impact of the changes made to the schemas may help environment administrators to plan these changes and propose better alternatives when dealing with more complex schema changes causing a greater impact on the environment. The relevance of this work is related to real cases that require evolution of analytical databases (Data Warehouse) in mobile computers in which the users keep their own subset of Data Warehouse information to support their business processes.
