What Is Architecture?

The principles and standards that define how an application is organized

Captured not in code, but the code itself The result of analysis and design The foundation of application documentation Forward-looking

Why Is Architecture Important?

Architecture represents foundational design decisions– Hardest to change later on– Most critical to get right up front

Architecture serves as a foundation for the capture of intellectual property– Code– Business rules/domain expertise

A vehicle for communication– Sponsors– Developers– Project Managers– Documenters– Customers

The blueprint for a successful software application

What is a “Reference Architecture”?

Taken at literal value –– “Architecture”: The structure of an application

– “Reference”: Intended to provide guidance Reference Architectures are for knowledge

transfer and learning– Applications/code

– Documents

– Diagrams Describing and demonstrating best practices for

software application development

Guidance for success
