1. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial

2. Um modelo para manutenção de esquema e de dados em data warehouses implementados em plataformas móveis. / A model to schema and data maintenance in data warehouses implemented at mobile platforms.
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

3. DistribuiÃÃo dos Dados em Ambientes de Data Warehousing: O Sistema WebD2W e Algoritmos Voltados à FragmentaÃÃo Horizontal dos Dados
A data warehousing environment consolidates data of interest from distributed, autonomous and heterogeneous information sources into a single database, called as data warehouse. This environment guarantees efficiency and flexibility in the recovery of strategic information turned to management and decision-making processes, and maintains integrated data in t
