Desenvolvimento de um ambiente de consultas em Big data considerando um esquema estrela de dados.

Abstract

The generation and storage of information in digital format has grown considerably in recent years. These data come from the most diverse origins and represent themselves in various forms. This new concept denominated as Big Data proposes to us new challenges when it comes of data storage, the query and visualization. Thus forms to represent this information should be implemented to help organizations in the analysis of these data and can be a complement to the systems of Data Warehouse that many companies already have. The objetive of the work is to developing a query environment in a Big Data considering the star scheme of Data, the star scheme that normally regulates the organization of facts and dimensions in a Data Warehouse. Therefore, in order to capture data and load the Big Data, the Ontoclipping, a tool that uses ontologies to improvement and faciliate the work of information retrieval on the web. To integrate Data Warehouse to a Big Data, a mapping between dimensions of the star scheme with the ontologies used in Ontoclipping as allowing the user to query and display the results collected both in Big Data as in the Data Warehouse.
