In some software systems, users can write scripts, macros, or rules that access and compose the basic features of the system in new ways.

Multiple perspectives are necessary to capture the complete behavior and development of a software system.

It should be obvious that the programming language paradigm used to implement a system would affect the architectural style of that system.

Many organizations in our lives work by some kind of hierarchy, a business, a government, a student society.
