The Department of Defense Architecture Framework (DoDAF) is an architecture framework for .. DoDAF versions thru used the CADM meta-model, which was defined in IDEF1X (then later in UML) with an XML Schema derived from the. Core architecture data model (CADM) in enterprise architecture is a logical data model of Core architecture data model (CADM) is designed to capture DoDAF architecture information in . DoD Architecture Framework Version Volume 1. The purpose of the DoDAF Decision-Support Overlay is to accomplish that by pragmatically aligning architecture data with the data requirements of the.

The horizontal line in each box separates the primary key attributes used to find unique instances of the entity from the non-key descriptive attributes. To facilitate the use of information at the data layer, the DoDAF describes a set of models for visualizing data through graphic, tabular, or textual means. Definitions and Guidelines”, “II: For this reason, it may be necessary to include some high-level Systems View SV architecture data as overlays or augmenting information onto the Operational View products.
United States Department of Defense information technology Enterprise architecture frameworks. The approach depends on the requirements and the expected results; i. A pure Operational View is material independent.
It was initially published in as a logical data model for architecture data. Higher priority inputs are usually processed before lower priority inputs.
Core architecture data model – Wikipedia
From Wikipedia, the free encyclopedia. PST on Saturday, November 18, Over a typical 2-year period, the U. Enterprise architecture Systems engineering Military acquisition Modeling and simulation. Retrieved from ” https: The DoDAF provides a foundational framework for developing and representing architecture descriptions that ensure a common denominator for understanding, comparing, and integrating architectures across organizational, joint, and multinational boundaries.
It broadened the applicability of architecture tenets and practices to all Mission Areas rather than just the C4ISR community. Examples of responses include: The major elements of a core architecture data model are described as follows: Node is a complex, logical concept that is represented with more concrete concepts.
Processes producing multiple outputs can include probabilities totaling percentunder which each output would be produced. In addition to graphical representation, there is typically a requirement to provide metadata to the Defense Information Technology Portfolio Repository DITPR or other architectural repositories. Under DODAF 2, which became operational inthe collections of views are now termed ‘viewpoints’ and no longer views.
The entity name is outside and on top of the open box. This Architecture Framework is especially suited to large systems with complex integration and interoperability challenges, and it is apparently unique in its employment of “operational views”. The CADM defines the entities and relationships for DoDAF architecture data elements that enable integration within and across architecture descriptions. In this manner, the DM2 supports the exchange and reuse of architectural information among JCAs, Components, and Federal and Coalition partners, thus facilitating the understanding and implementation of interoperability of processes and systems.

As illustrated in the figure, boxes represent entities for which architecture data are collected representing tables when used for a relational database ; they are depicted by open boxes with square corners independent entities or rounded corners dependent entities.
State transitions in executable operational architectural models provide for descriptions of conditions that control the behavior of process events in responding to inputs and in producing outputs. It establishes a basis for semantic i. This document addressed usage, integrated architectures, DoD and Federal policies, value of architecture, architecture measures, DoD decision support processes, development techniques, analytical techniques, and the CADM v1.
The symbol with a circle and line underneath indicates subtyping, for which all the entities connected below are non-overlapping subsets of the entity connected at the top of the symbol.
Department of Defense Architecture Framework
Some graphical DoDAF views: It broadened the applicability of architecture tenets and practices to all mission areas rather than just the C4ISR community. It enables the effective comparing and sharing of architecture data across the enterprise, contributing to the overall usefulness of architectures.
The Department of Defense Architecture Framework DoDAF defines a standard way to organize a systems architecture into dodad and consistent views. Otherwise there is the risk of producing products with no customers. There are many different approaches for creating an integrated architecture using DoDAF and for determining which products are required.
Conformance with the CADM ensures the use of common architecture data elements or types.
Only a subset of the full DoDAF viewset is usually created for each system development. The response may vary depending on the current state and the rule set or conditions.
The Department of Defense Architecture Framework DoDAF is an architecture framework for the United States Department of Defense DoD that provides visualization infrastructure for specific stakeholders concerns through viewpoints organized by various views.
Examples of distribution strategies include: All view AV products provide overarching descriptions of the entire architecture and define the scope and context of the architecture. The CADM describes the following data model levels in further detail: Systems and services view SV is a set of graphical and textual products that describe systems and services and interconnections providing for, or supporting, DoD functions.
The depicted conceptual relationships shown in this diagram include the following among many others: SV products focus on specific physical systems with specific physical geographical locations.
Adherence with the framework, which includes conformance with the currently approved version of CADM, provides both a common approach for developing architectures and a basic foundation for relating architectures. These histograms are used to perform dynamic impact analysis of the behavior of the executable architecture. The DoDAF provides products as a way of representing the underlying data in a user-friendly manner. The actual sequence of view generation and their potential customization is a function of the application domain and the specific needs of the effort.
It identified and defined entities, attributes, and relations.
