Functional architecture ontology
This section identifies the nomenclature used to describe a functional architecture. 
According to Dictionary.com, an ontology is “the hierarchical structuring of knowl-
edge about things by subcategorizing them according to their essential qualities.” 
Therefore, the following “things” are entities used in describing and documenting 
the functional architecture. The labels are not specific to software engineering and 
are applicable to describe the functionality of any human-made product.
