RESUMO
The purpose of this dissertation is to present and to analyse ways to access objects in distributed environments, as a means to optimize and to facilitate to the client the access to the distributed system services. The specifications of the open distributed processing (ODP - Open Distributed Processing), the models of the application program interfaces (APIs - Application Program Interface) and commercial distributed plataforms were considered for the development of this work. The first proposed specifies an application program interface, using an oriented-object methodology, to offer a group of services supplied by the existent commercial distributed plataforms to the development, running and management of distributed applications. The second proposed is based on the CORBA (Common Object Request Broker Architecture) architecture, where we specified an access scheme to the objects of this environment. This scheme is based on implementation and interface repositories. This scheme provides that the repository information is got quickly and safely. Then the Middleware layer provides distributed processing facilities to the applications, specially to the applications of the Multiware plataform, that is being developed at UNICAMP
