Resumo
Durante os últimos anos, um grande volume de dados foram armazenados através de sistemas transacionais, ou mesmo até por Sistemas de Apoio à Decisão.
Surgiram novas tecnologias e técnicas para prover melhores serviços para o armazenamento e recuperação destes dados. Surgem também novas técnicas e conceitos para aproveitar esta imensidão de dados operacionais e transformá-los em dados gerenciais, e assim permitir aos executivos das empresas uma maior gestão do negócio.
Dentre as técnicas e conceitos novos surge o Banco de Dados Multidimensional visando oferecer suporte e otimizações matemáticas, estatísticas e de tempo, e dentre outros aspectos a simplicidade deste ambiente, permitindo assim a interação com os usuários, além da integração com ferramentas de planilha eletrônica.
Para compreender o conceito e as técnicas de modelagem para o Banco de Dados Multidimensional buscou-se apresentar as técnicas e conceitos da modelagem Relacional bem como um breve comparativo entre ambas as modelagens, a Relacional e a Multidimensional.
Além das técnicas para projetos de Banco de Dados Multidimensional apresentou-se alguns conceitos sobre este tipo de banco de dados, assim como alguns produtos existentes no mercado.
E para uma melhor compreensão, teceu-se um pequeno Estudo de Caso, baseado nos conceitos e técnicas apresentados, e também algumas possibilidades para futuros estudos relacionados ao tema.
During the last years, a great volume of data was stored through transactional systems, or same even for Systems of Support to the Decision. New technologies and techniques appeared to provide better services for the storage and recovery of these data: It also appears new techniques and concepts to take advantage of this immensity of operational data and you transform them in managerial data, and like this to allow to the executives of the companies a larger administration of the business. From among the techniques and new concepts the Multidimentional Database appears seeking to offer support and mathematical optimization, statistics and of time, and from among other aspects the simplicity of this sets, allowing like this the interaction with the users, besides the integration with tools of electronic spreadsheet. To understand the concept and the modeling techniques for the Multidimentional Database it was looked for to present the techniques and concepts of the model Relational as well as a brief one comparative among both modeling, Relational and Multidimentional. Besides the techniques for Multidimentional Database projects came some concepts on this database type, as well as some existent products in the market. And for a better understanding, it was woven a small Study of Case, based on the concepts and presented techniques, and also some possibilities for future studies related to the theme.
