The Department of Defense Architecture Framework (DoDAF) is an architecture framework for the United States Department of Defense, that provides structure for a specific stakeholder concern through viewpoints organized by various views.
DoDAF defines a set of views that act as mechanisms for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through tabular, structural, behavioral, ontological, pictorial, temporal or graphical means.
It is especially suited to large systems with complex integration and interoperability challenges, and is apparently unique in its use of operational views detailing the external customer's operating domain in which the developing system will operate.
UPDM is an Object Management Group (OMG) initiative to develop a modeling standard that supports both the USA Department of Defense Architecture Framework (DoDAF) and the UK Ministry of Defence Architecture Framework (MODAF). The modeling standard is called the Unified Profile for DoDAF and MODAF (UPDM).
