Resumo
O Data Warehouse (DW) surgiu como base para os Sistemas de Suporte à Decisão (DSS) integrando fontes de dados dos sistemas transaccionais. A sua crescente popularidade reflecte a necessidade das organizações em obter informações analíticas derivadas dos seus sistemas transaccionais. Ou seja, com a chegada de novas ferramentas tecnológicas de análise de informação, os dirigentes das organizações começaram a exigir dos sistemas transaccionais respostas às suas solicitações, mas como estes sistemas foram desenvolvidos para garantir a operação da organização não estão preparados para gerar e armazenar as informações estratégicas necessárias a um Business Intelligence (BI) eficiente. O DW tem características diferentes do ambiente tradicional e é construído com o objectivo de suprir as necessidades de processamento analítico das organizações. Considera-se que os projectos de DW têm mais hipóteses de sucesso quando desenvolvidos através de uma metodologia consistente que guie o projectista durante as várias fases do projecto. As instituições de ensino superior em Portugal não são excepção ao referido anteriormente. Existe neste tipo de organização uma grande quantidade de sistemas que auxiliam a gestão das suas actividades rotineiras, onde a possibilidade de propiciar aos seus administradores acesso a informações institucionais em tempo real num ambiente único a partir de qualquer computador ligado à Internet, permitirá auxiliar às tomadas de decisão. Assim, com a metodologia proposta foi desenvolvido um caso de estudo com a finalidade de verificar e avaliar a aplicabilidade da metodologia num instituto politécnico.
The Data Warehouse (DW) emerged as a basis for the Decision Support System (DSS) integrating data sources of transactional systems. Their growing popularity reflects the need for organizations to obtain analytical information from their transactional systems. Such systems have different features of traditional environment and are built with the aim of addressing the needs of analytical processing of organizations. It is considered that DW projects have more chance of success if developed through a consistent methodology that guides the designer during the various phases of the project. That is, with the arrival of new technological tools for analyzing information, the leaders of the organizations began to require of transactional systems answers to their requests, but these systems were developed to ensure the operation of the organization and are not prepared to generate and store the strategic information necessary for a Business Intelligence (BI) efficient. Higher education institutions in Portugal are no exception. These institutions have several systems that help the management of their routine activities, where the ability to provide their administrators access to information in real time in a single environment from any computer connected to the Internet, will help the acquisition of decision. So with the proposed methodology was developed a case study for the purpose of verifying and assessing the applicability of it in a polytechnic institute.
