CORBA상에서의 그룹객체의 구현에 관한 연구 = An Implementation of Group Objects in CORBA

다국어 초록 (Multilingual Abstract)

As an application software in distributed computing environment becomes large, the number of objects to be created increases drastically and the interfaces among them become very complex. The concept of group object resolves this problem to some extent by grouping a set of related objects, encapsulating them, and controlling their interfaces systematically. In this paper, we propose an implementation model of the group object concept in CORBA, which is a standard middleware for developing distributed application software on heterogeneous networks. To support group objects, we extends CORBA ORB without modifying its internal structure for the compatibility with existing CORBA applications. And we devise an interface definition language by extending CORBA IDL to describe group objects in a language-independent style, which is one of the most important characteristics in CORBA. Finally, we experiment the implementation model on a CORBA ORB compliant product which supports the Java language.
