Software System Engineering Dr. M.E. Fayad, Professor Computer Engineering Department, Room #283I College of Engineering San José State University One Washington Square San José, CA 95192-0180 http://www.engr.sjsu.edu/~fayad © M.E. Fayad 2000-2005 SJSU -- CmpE

Lesson 21: Stable Model-Based Architectures © M.E. Fayad 2000-2005 SJSU – CmpE --- M.E. Fayad

3 Lesson Objectives Explore the base for reuse Understand model-based architecture Explore the base for reuse Understand the impact of software stability on reuse Apply the software stability in a case study 3 © M.E. Fayad 2000-2005 SJSU – CmpE --- M.E. Fayad

4 Why reuse? Size of Software product increases fast Software product becomes more and more complex Existing large amount of commonality from one software to another 4 © M.E. Fayad 2000-2005 SJSU – CmpE --- M.E. Fayad

More on Why Software Stability Model? Model is critical for the software Model reuse is efficient and productive Traditional model is hard to reuse because it is unstable under changes SSM is naturally suit for model reuse for its stability and adaptability 5 © M.E. Fayad 2000-2005 SJSU – CmpE --- M.E. Fayad

6 Case Study Material Transportation Scheduling System © M.E. Fayad 2000-2005 SJSU – CmpE --- M.E. Fayad
