Enterprise Application Architecture Styles and their CombinationIt has been noted by pioneers in the patterns community that the patterns and rules in a pattern language combine to form an architectural style. While the concepts of patterns and pattern languages have come to be widely understood and appreciated in the software development profession over the last 14 years, the notion of architectural style has gained comparatively little mind share.
But the software development profession, particularly the enterprise application architecture community, could benefit from greater attention to the study of architectural style. Communication would be improved, for example, if we had ubiquitous language for identifying different architectural styles, and agreeing on their distinctive characteristics. That would allow us to compare and contrast different systems, and possibly develop a classification system for enterprise applications.
This seminar talk will traverse the territory of architectural style within enterprise applications. Beginning with a brief survey of the prior art, it will propose candidate names and typical characteristics of architectural styles observed in the wild. Approaches to classifying architectural styles will be addressed, and potential benefits of classification reviewed. Finally the talk will treat the combination of different architectural styles, focusing on the use of SOA and DDD together as an example.
