5. Component-based software engineering • How do you define a “Component”? • How do you define “Component-based software engineering”? Component-Based Software Engineering Dr R Bahsoon

6. What is a Component? • Several definitions of a component in literature, however everyone agrees that a component is a piece of software… But this requires clarification! Component-Based Software Engineering Dr R Bahsoon

7. What is a Component? • Components provide a service without regard to where the component is executing or its programming language • A component is an independent executable entity that can be made up of one or more executable objects • The component interface is published and all interactions are through the published interface Component-Based Software Engineering Dr R Bahsoon

8. What is a Component? • There are many other definitions of components: • Consideration of CBSE from different viewpoints and focus on different aspects of software engineering • Design phase: components as reusable design parts • Architecture phase: (e.g. UML components; ADL component) • Implementation phase: components confirmed to a specific component model • At run time could be binary packages, distributed components • Business aspects (business components, service components, COTS components) Component-Based Software Engineering Dr R Bahsoon

9. About CBSE(1/4) • Introduces Components-Based Software Engineering (CBSE) Vision & dream! Reality Component-Based Software Engineering Dr R Bahsoon

10. About CBSE(2/4) • Motivation for CBSE • Develop software systems as assemblies of components • Reuse-driven & market-driven software development • Easing maintenance and evolution: design for change! • CBSE related concepts, views, and perspectives • CBSE challenges Component-Based Software Engineering Dr R Bahsoon

11. About CBSE(3/4) • Describes the principles and practices of systematically engineering software systems from components • CBSE process models vs. classical models • CBS lifecycle, reuse approach, Unified Process • Requirements & design • Requirements engineering approaches to CBSE • Describes Unified Modeling Language (UML) notations to the specification, design, and modeling of components-based software • Component-based software architectures • Styles, specification, refinements, and paradigms (e.g. Service-oriented architectures, middleware-induced software architectures, Model-Driven Architectures) • Dependability issues in CBSE Component-Based Software Engineering Dr R Bahsoon

12. About CBSE(4/4) • Testing & certification issues in components-based software • Overview of the current technologies, component models, and frameworks supporting CBSE • The Microsoft way - .NET • The OMG way - CORBA • The Sun way – J2EE • Other advanced topics, if time permits • Invited presentation(s) • Readings, discussions, and your presentations Component-Based Software Engineering Dr R Bahsoon

13. Assessment • Assessment • 1.5 hr examination (80%) • Choice • Compulsory questions: concepts, processes, UML modelling… • Reflection questions: presentations-related… • Continuous assessment (20%) • Group presentations, discussion, and reflection on some advanced CBSE topics • Presentation schedule & topics will be posted soon • Peer and self assessment (friendly and supportive “shepherding” style) • Workshop-like style: interactive • Group modelling exercise – due by the end of the term • Courtesy face-to-face feedback providing training for your examination • “Small” discussion/reading exercises • Resit (where allowed) by examination only with the continuous assessment marks carried forward Component-Based Software Engineering Dr R Bahsoon

14. Meetings • Lectures & meetings • Tuesday 3pm, UG40, Computer Science • Tuesday 5pm, LG32, Learning Centre • Two non-timetabled hrs/week: use these for meetings with your group • Office Hours: • Open door policy or follow my timetable (TBA) • Appointment by e-mail r.bahsoon@cs.bham.ac.uk Expect a rapid reply for any e-mail (a word of trust!)
