Estudo do modelo de computação orientada a serviços e sua aplicação a um sistema de mineração de dados

Abstract

This work presents a study on the applicability and performance of WebServices as a materialization of Service Oriented Architectures (SOA), witha case study on a real service oriented system. In this concern, the majorcontribution was to show the steps necessary to design and build serviceoriented applications, discussing difficulties along the way and possiblesolutions for questions that are part of this new programming model.For the real application that was to be the case study, we decided to buildan interactive, multi-user data mining system, Tamanduá (Anteater). Datamining and knowledge discovery applications are becoming extremelyimportant nowadays. The development of a distributed system for mininglarge data bases includes many interesting requirements, such as findin gand using remote services dynamically, which can be directly mapped tothe SOA model. The result was a system based on Web Services which meets the requirements for distributed data mining. The extensibility andscalability of the platform were measured to confirm the viability and thepotential of this kind of system, as well as the advantages of SOA. The Tamanduá platform is operational and the experiments presented showthat its performance is satisfactory and it can be expanded to meet anincreasing user demand. The performance analysis can also be useful as support for future work in the area of Web Services.
