Class Scheduling Framework Using Decorator and Façade Design Pattern

Class scheduling problem has been regarded as one of the most difficult yet important challenge for developers involved in 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 system, this paper presents an object-oriented approach to designing a class scheduling paradigm using decorator and facade structural design patterns. 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 the Java programming environment. The result of the study is a simplified method for designing an efficient and reusable component for the class scheduling model.
