| Resumo | The purpose of this paper is to present a study of a distributed object application to the satellites Simulator, present in the National Institute for Space Research - (INPE), Control Center of Satellites, in an attempt of adjusting it, to the trends of technological evolution. With the intention of improving this application, techniques for a better modeling of the distribution of these objects are also studied. The Satellites Simulator is a software with the purpose to train operators in its control and tracing , and to provide a real environment to perform the tests of acceptance of the software of satellites system control. Since it operates in a centered system, the Satellites Simulator presents some limitations, related to availability, fault tolerance, interoperability, flexibility in taking care of the different situations of control, that turn out to be obstacles to the performance of the simulation process. It is observed that many of this limitations can be solved or minimized through the existing features in the distributed object paradigm. Distributed object represents the evolution of the conventional object. It has an environment controlled by middleware, providing advantageous properties as distribution, transparency, fault tolerance, availability, concurrency, and better performance. To conserve these same features, in a client/ server environment, without distribution of objects, significant efforts would be demanded to implement and control the many necessary interfaces for the interconnection of these systems. In the last years, companies of software are offering in the market, some new standards to be applied to the distributed object systems. These standards become, each year, more enclosing and efficient. However it is observed a deficiency in the aspect of how to model correctly this distribution, in other words, how to distribute the objects according to the application features and the user necessities, exploring more actively this technology advantages in order to reach a better quality. Besides exploring the features of the objects distribution applied to the Satellites Simulator, it is intended to construct an analysis, through the modeling of distribution of objects, observing the necessities and aspects presented by the application. Then , some techniques are proposed, for example: models based in Use Cases , fault Tolerance and random form, that establish criteria and different forms of how to distribute better involved objects in the Satellites Simulator. The initiative does not have as an objective to point what is the best technique to be used. The efforts will be concentrate in raising the advantages and disadvantages of each technique, exploring qualitative and quantitative factors involving performance, availability, data traffic, etc. So , the foreseeing of the behavior of the objects in the application, examining important individual factors or when related to the other objects and in different aspects, can bring a contribution for a better organization of them in the Satellite Simulator. It is expected that this analysis points to the necessity of modeling correctly the objects distributed, so that it gets important profits regarding the efficiency of the application. |
