Module 3: Components of Enterprise Architecture

The Four Primary components of Enterprise Architecture are:

1. Enterprise Business Architecture
2. Enterprise Information Architecture
3. Enterprise Solution Architecture
4. Enterprise Technical Architecture

Documents the business strategy, governance, organization and business functions. Provides a holistic view of our state government from a business perspective.

Enterprise Business Architecture (EBA)

Establishes a baseline that defines which organizations perform these functions.

Enterprise Business Architecture (EBA)

Provides a framework, model, and method to enhance each agency's ability to quickly discover access, and understand data, while creating information needed to support critical agency business function decisions.

Enterprise Information Architecture (EIA)

Gives a common reference model of citizens, businesses, members of General Assembly, current and future administrations, and other interested parties that helps define the business of state of government.

Enterprise Business Architecture (EBA)

EIA must have three components that contain information about the enterprise's data assets:

-Data sharing
-Data description
-Data context

Information Exchange and Query
Points - Information generated/required by a Unit of work and is subsequently passed to
another unit of work.

Data sharing (How do I exchange the data?)

Data description (What does the data mean?) can be identify into:

structured, semi structured, unstructured

It is an organized description of data to convey semantic understanding usually through an entity relationship diagram.

Structured

Has characteristics of both Structured and Unstructured such email.

Semi Structured

More free-form format such as unstructured text.

Unstructured

Data Context (How do I find the data and
access it?):

Subject Area, Information Class

Broad Categories of
data that supports business
processes.

Subject Area

Groupings of lines of business or community of interest.

Information Class

Collection of information systems supporting or related to the business functions defined by EBA and the enterprise business model.

Enterprise Solution Architecture (ESA)

Includes applications and components that are purchased or custom-developed. Also known as Enterprise Application Architecture

Enterprise Solution Architecture (ESA)

Is a consistent set of IT standards and models

Enterprise Technical Architecture (ETA)

What does Enterprise Technical Architecture (ETA) do?

- Reflect and support EBA, EIA, and ESA
components.
- Guides the engineering of emerging IS and technology infrastructure.
