Question 1

Which statement best describes the relationship between views and viewpoints in ISO/IEC 42010?

Accepted Answer

A viewpoint is a specification that governs how a view is constructed and what concerns it addresses

Answer

ISO/IEC 42010 defines a viewpoint as the convention or template used to construct a view, which is the actual artifact documenting one perspective.

Question 2

What is the key difference between a 'whitebox' and 'blackbox' description in arc42's Building Block View?

Accepted Answer

Whitebox shows internal structure; blackbox shows only external interface and behavior

Answer

A whitebox description reveals the internal components and relationships of a building block, while a blackbox description hides internals and shows only its interface.
