Reuse Based On The Whole Process Of Software Development Model And Its Applications

With scale and the complexity of the software system increased, the importance of software development model is more obvious. The traditional software development model has played the huge role in the system development, however they all considered little of the code reuse and the system reconstruction. The essence of software reuse is to generate new software system whose ingredient had been used in the old software system, thus the efficiency and the quality of the software development is enhanced, and duplicated works is avoided. General software reuse includes the reuse about the project organization, software demands, software designs, project documents, software realizations, test methods and test cases etc...Combining software reuse with the software development model, it must be able to enhance the system quality, also has the certain research value theoretically.The article discusses the software reuse and the traditional software development model, and it built a new all stage software development model based on reuse, which causes the reuse in system development to be consider fundamentally, and increase efficiency in software project and project management, then practiced and confirmed this model based on an actual IERP system development example.The model can be considered a new optional project in the development of large-scale software.
