UNIT I [10]

Definition - software components, COTS and infrastructure - Moving from project-centric to architecture-centric software engineering - software variability management.

UNIT II [10]

Software architecture design method : Top-down versus bottom-up design - functionality-based architecture design - variability analysis - architecture evaluation and assessment - scenario-based evaluation - simulation-based evaluation - experience-based evaluation - architectural styles - architectural patterns - applying design patterns - convert quality requirements to functionality.


Design Patterns - Evolution patterns - Software artifact evolution processes: interdependence, dependence or independence - Case studies: examples and experiences - Use of Java Beans.
