• Heterogeneous
• Large number
• Development life cycle

3. Goal
3
“Enable development** of SCC applications with
minimal effort by various stakeholders* involved in
development process”
**Development -- “a set of related activities that leads to a production of a software product.’’ [Ian Sommerville,
Software Engineering (9th edition) , 2010]
*Stakeholders in software engineering to mean – people, who are involved in the application development.
Examples of stakeholders defined in [Taylor et al., Software Architecture, 2009] are software designer,
developer, domain expert, technologist, etc.

attributes that describes it, and its state that is
relevant from a user or an application perspective.”
