model presents the business using a functionally driven approach. The Lines of Business
and sub-functions that make up the BRM represent a departure from previous models of the
Federal government that use antiquated, stovepiped, agency-oriented frameworks. The
BRM is the first layer of the FEA, and it is the main viewpoint for the analysis of data,
service components, and technology.
(3) Service Component Reference Model (SRM). The SRM is intended to support the
discovery of government-wide business and application service components in IT
investments and assets. The SRM is structured across horizontal and vertical service
domains that, independent of the business functions, can provide a leverageable foundation
to support the reuse of applications, application capabilities, components, and business
services. The Coast Guard EA will participate in service component reuse where it
enhances mission or support activity performance. It is expected that most of this alignment
activity will take place within the Department of Homeland Security (DHS) vice
government-wide.
(4) Data and Information Reference Model (DRM). The DRM describes, at an aggregate level,
the data and information that support program and business line operations. The model aids
in describing the types of interaction and exchanges that occur between the Federal
government and its various customers, constituencies, and business partners. The DRM
categorizes the government's information along general content areas and decomposes those
content areas into greater levels of detail. The DRM establishes a commonly understood
classification for Federal data and leads to the identification of duplicative data resources. A
common data model streamlines the processes associated with information exchange within
the Federal government between the government and its external stakeholders.
(5) Technical Reference Model (TRM). The TRM is a component-driven, technical framework
used to identify the standards, specifications, and technologies that support and enable the
delivery of service components and capabilities. It provides a foundation to describe the
standards, specifications, and technologies to support the construction, delivery, and
exchange of business and application components (service components) that may be used
and leveraged in a Component-Based or Service-Oriented Architecture. The TRM unifies
existing Agency TRMs and electronic Government guidance by providing a foundation to
advance the reuse of technology and component services from a government-wide
perspective. The Coast Guard EA includes a TRM that aligns with the DHS TRM but still
provides the flexibility required to meet mission and support needs.
d. Enterprise Standards Profile (ESP). The ESP is a comprehensive set of technical standards for
the Coast Guard. Its organization reflects the categorization of technology building blocks
defined in the Coast Guard TRM, as well as the sometimes-unique requirements of specific
operational domains. The TRM is the accepted representation of the generic components of the
Coast Guard system-of-systems and applies to all C4&IT systems in the Coast Guard
"enterprise." Within that context, the ESP references the published technical or procedural
standards and the products that the Coast Guard has selected and approved to implement those
components.
e. Enterprise Data Architecture. The component of the overall EA that describes the information
used in mission and mission support activities, the data managed by C4&IT applications and
infrastructure, and data standards.
f. Enterprise Data Management (EDM). The EDM is activities and practices necessary to manage
data as an asset throughout an enterprise. EDM includes establishing data practices and plans,
