Quick Reference

Acronym for hierarchical object-oriented design. HOOD was developed specifically for the European Space Agency and very closely follows the structure of the Ada programming language. It provides diagram notations to depict nested packages and tasks; it also provides specification of these items in terms of procedures, functions, variables, types, etc. It indicates how higher-level objects are decomposed into lower-level objects and also how the interface of the high-level object is mapped to the interface(s) of lower-level objects.
