The Research Of Pattern-Oriented Software Architecture

Design pattern is one of the software-reuse technologies, which derives fromthe conclusions of others' design experiences. Every design pattern is testified to beuseful. J2EE design pattern is a product combining J2EE platform with designpattern, which not only has advantages of the design pattern but also is morepracticable than the specific patterns. Through applying the method ofPattern-Oriented Analysis and Design (POAD) and utilizing UML class diagrams assystem constructors, we may rapidly develop a reliable large-scale softwareapplication. This paper introduces the concepts of architecture, framework anddesign pattern and shows the relationship. By utilizing the method of POAD andcombining J2EE design pattern, we construct a Human Resource ManagementSystem, which has more robustness,expansibility and maintainability.
