CORBA-Based Class Scheduling Framework Using Decorator and Facade Design Patterns

Abstract

Class scheduling problem has been regarded as one of the most difficult yet important challenges for developers developing timetabling applications. Different algorithms or schemes were devised to address such problems. Yet, considering the growing complexity of the input factors, it contributes to difficulties in maintaining the said system. In order to aid in the development and maintenance of such a system, this paper presents an object-oriented approach to designing a class scheduling paradigm using decorator and facade design patterns with CORBA architecture. This technique was based on the concepts of several existing object-oriented components of Windows GUI platforms. The paradigm designs are expressed using Unified Modeling Language (UML) and illustrated in a Java programming environment. The result of the study is a simplified method for designing an efficient and reusable component for the class scheduling model.
