For TOGAF readers, one item of vocabulary still has to be explained. TOGAF often refers to solution
architecture. Here, the term “architecture” designates a description, and more precisely a logical view,
as opposed to the “solution,” which represents a technical reality. This distinction can be clearly seen in
the terms “Architecture Building Block” and “Solution Building Block” (respectively ABB and SBB).
The logical specification of an element is an ABB, while its physical equivalent is a SBB. These two
types of element are present in the architecture repository, which enables either the documentation or
the physical component to be reused, according to the context.
