DQ2 – What is Enterprise Architecture
Read the article at this link – http://www.information-management.com/news/enterprise-architecture-ERP-BI-SIM-10021528-1.html?pg=1 Discuss the views of the four panelists, compare to the knowledge gained from your other readings. What are key similarities, key differences?
There are terms that you need to be familiar with for this class. Please take the time to understand what is described below, do further research if needed, and ask questions if you have any. The descriptions below are intended to (1) level set and (2) be a starting point if you need more info.
We will break ‘enterprise architecture’ into segments. These segments are interchangeably referred to as ‘domains’, ‘sub-architectures’, and/or ‘perspectives’. These terms are synonymous. The four most common domains/sub-architectures/perspectives, and the ones we will focus on, are (1) business (2) application (3) data (4) technology. (Note: I will typically use the term domain.)
There are many ‘architecture’ terms…and these are not used interchangeably.
Enterprise Architecture – conceptual blueprint that defines the structure and operation of an organization. The blueprint describes the strategic business, information, process, and technology changes necessary to execute corporate objectives/strategies and enable the defined business capabilities.
Reference Architecture – template solution for an architecture for a particular ‘area’. The ‘area’ can be a specific industry and/or a domain within an industry and/or a business capability. Many times Reference Architectures are available on the web.
Solution Architecture – combination of role, process and documentation that is intended to address specific problems and requirements, usually through the design of specific information systems or applications. This is the architecture of the solution, as the name specifies.
Application/Data/Technical/Network/Security/Integration Architecture – these are domain-level architectures. Domain-level architectures can be subsets of both the Reference Architecture and the Solution Architecture.
Let’s give an temporal example to pull this together.
Important Terminology
The Enterprise Architect developed an Enterprise Architecture that defined the business capabilities and the strategic technologies that would be needed to meet the business objectives. One of the strategic technologies on the Enterprise Architecture roadmap is to move to a hybrid (on premise and off premise) cloud environment.
A Reference Architecture was identified. Please see this link for an example of a Reference Architecture
Using the Reference Architecture, a Solution Architecture was developed which identified specific vendors, hardware, and software. Please see this link for an example of a Solution Architecture
Specific details were developed in Technical Architecture, Security Architecture and Network Architecture diagrams
