Introduction to Seminar Topic on Distributed Software Systems with CORBA:
In our growing technological needs the distributed database system has become a wide spread. To meet challenges of providing transparency and security to the computers in the network the object management group came with the corba architecture. The distributed software systems appear as a single coherent system for the user. In this paper we will see types of distributed architectures and the characteristics of designing a distributed system.
Brief on Corba:
In distributed software systems we find client server architecture in which the client interacts with the server to use the shared resources. Whereas in distributed object architecture the interaction between the servers and clients is irrelevant. In distributed software systems the components are located in networked computers and they communicate by passing messages in between them.
The communication between the systems is made by passing messages and the systems use a shared memory for running the threads. Common object request broker architecture is a middle ware software application which allows the application programs to interact with each other irrespective of their programming language. The object modeling architecture consists of object model and reference model which makes the hardware and software specification to fit so as to make interactions with the objects.
The cobra architecture is a suitable architecture and has many advantages than DCOM. The DCOM architecture is a Microsoft package developed by group of developers, whereas the OMG is developed by members from all over the word as this is a open group and it developers working on different platforms.
