The EA group
IASA director of technology
3: Architecture - Oxford “The art or science of building or constructing edifices of any kind for human use…”
“The special method or ‘style’ in accordance with which the details of the structure and ornamentation of a building are arranged.”
4: What is architecture IEEE “The organizational structure of a system or component.”
IEEE Standard 610, “Standard Computer Dictionary: A Compilation of IEEE Standard Computer Glossaries”
“The fundamental organization of a system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution.”
IEEE Standard 1471, “IEEE Recommended Practice for Architectural Description of Software-Intensive Systems.
5: What is system architecture Design:
How each component should be build
OO, Class, design patterns etc’.
Differences between architecture and design
Many different designs may address the same need
Different architectures imply different needs
Sample from reality: House
Architecture: number of rooms, main structure, character, guiding lines.
Design: interior design, rooms structure, electricity, etc’
