Research Of The Theory Of Software Patterns And Its Applications In Application Telephony Voice Services System

In recent years, the software pattern discipline, which can solve effectively the problems of reusing software design strategies, and which aims at creating design handbooks like other engineering field for software developers by documenting excellent achievements of software system designing, has been one of the most popular topics in the field of software engineering. This thesis focuses on the research of the basic theory of software patterns and its application in the development of one real software system, Application Telephony Voice Services System. In the paper the basic theory of software patterns was summarized systematically-the source of the software pattern theory, the definition and the elements of pattern, the description style and qualities of software patterns, the pattern language, the pattern categories, and the comparison of the software and other correlative concepts, the classification of the software patterns, the introduce of software patterns and design patterns. It was also introduced that how to design Application Telephony Voice Services System with the use of software patterns-developing the architecture with the use of software architecture patterns, the classes with the use of design patterns, the balance of the choice of design patterns and the experiences and lessons during the process..
