The Why and the Benefits of Architecture

DOI: 10.4018/978-1-4666-2527-3.ch009


The advantages of using architecture are examined from the information technology (IT) point of view in order to get a feel for the more general advantages that would apply to other areas of endeavour. Then IT architecture is reviewed in more detail to see in particular the levels of abstraction that are inherent in an architecture, moving from the general outline which shows the whole enterprise, down through progressive levels of detail, to the fine detail of actual implementation instructions. General architectural principles will be identified during the examination of the various architecture definitions.
