The DODAF 2.0 Architects Guide repeated DOD Instruction 4630.8 definition of an integrated architecture as "An architecture consisting of multiple views facilitating integration and promoting interoperability across capabilities and among integrated architectures." For the purposes of architecture development, the term integrated means that data required in more than one of the architectural models is commonly defined and understood across those models. Integrated architectures are a property or design principle for architectures at all levels: Capability,Component, Solution, and Enterprise (in the context of the DoD Enterprise Architecture (EA) being a federation architectures). In simpler terms, integration is seen in the connection from items common among architecture products, where items shown in one architecture product (such as sites used or systems interfaced or services provided) should have the identical number, name, and meaning appear in related architecture product views."
