Lesson ObjectivesObjectives3 Understand model-based architecture Explore the base for reuse Understand the impact of software stability on reuse Apply the software stability in a case study2003SJSU – CmpE --- M.E. Fayad L02-S4 Model-Based Arch.Size of Software product increases fastSoftware product becomes more and more complexExisting large amount of commonality from one software to another4Why reuse?2003SJSU – CmpE --- M.E. Fayad L02-S5 Model-Based Arch.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 adaptability5More on Why Software Stability Model?2003SJSU – CmpE --- M.E.
