No. of bitstreams: 1 DISS_2015_Rodicrisller Rodrigues.pdf: 2841204 bytes, checksum: 1323b47d2b97ea08fb569431626c4ed1 (MD5) Previous issue date: 2015-09-30 / Com a difusão dos dispositivos eletrônicos e a facilidade na troca de informações qualquer projeto científico usa dados oriundos de diversas fontes. Nesse contexto, dados científicos possuem aspectos semânticos inerentes ao seu processo de aquisição e área de domínio, de forma que para trabalhar com conjuntos de dados de origens diferentes é preciso resolver o problema da heterogeneidade semântica entre eles. Este trabalho enfoca a mitigação da heterogeneidade em dados científicos através do uso de infraestruturas virtuais de Computação Científica. O objetivo principal é demonstrar que soluções em nuvem computacional possuem os requisitos necessários para atender às demandas atuais de um contexto de Computação Científica e e-Science, de forma a facilitar a troca e interação de dados entre contextos heterogêneos / With the diffusion of electronic devices and the facility in exchange of information any scientific project uses data from different sources. In this context, scientific data have semantic aspects inherent to the process of acquisition and domain area, in such a way to work with different sources of data sets is necessary to solve the problem of semantic heterogeneity between them. This work focuses on the mitigation of the heterogeneity on scientific data using virtual infrastructures for Scientific Computing. The main objective is to demonstrate that computational cloud solutions have the necessary requirements to meet the current demands of the context of Scientific Computing and e-Science, in order to facilitate the exchange and interaction of data between heterogeneous environments.
