Abstract: Due to the rapid growth of the Internet, the Internet has given drastic influence and impact to not only our daily life but also enterprise information applications. Object oriented technology is widely used in software industry currently. The web-based and distributed object-based computing system is the integration of object-oriented technology and distributed computing, which is a new computing paradigm. This paradigm gives a new system architecture to be taken into consideration for solving the problems of interoperability and integration of heterogeneous systems. The Common Object Request Broker Architecture (CORBA) provides a standard infrastructure for performing objects interoperability transparently. However, a web-based, CORBA-based and distributed object architecture will stringently face the performances of CORBA objects binding and interoperability between CORBA objects, and objects management issues when the number of CORBA objects are soaring. In this paper, we propose CORBA based multithreading and Factory models to improve the performance of the distributed object architecture. Also, we give a web-based and CORBA-based telecommunication service order provisioning system to act as an experimental evaluation.
