Uma arquitetura distribuída baseada em web services para gerência e consulta de informações sobre transporte coletivo municipal

Abstract

The need to provide information on the Internet has driven the development of technologies that allow data exchange between applications. In order to perform the communication between applications with different characteristics, Web Services are used. In the context of information provision, there is the urban public transport system, which is a public service and requires publication of information. This information has the aim of facilitating the use of the service and are provided by the responsible department, however, usually, but not standardized. Sometimes, applications customers need this information to perform a computation and provide to users, but the way they are stored can become difficult to access and manipulation. Thus, this work focuses to build a tool to keep information and provide access to client applications. Creating a Web Service can be a solution, since it can provide methods for information management and consultation to other applications. Moreover, because the service is widely used, provided that there would be a great demand for access and that the fault tolerance was absent in the case of a single service provider. Therefore, a distributed architecture, which provided a data replication technique and a discovery dynamic of services, could expand the supply of such information and provide for fault tolerance.
