ZapThink recently published what may be the most frustrating column about SOA I've read to date - and I read a lot of frustrating SOA pieces. This article even frustrated Sam the hamster, whose cage is next to my desk, because I woke him up yelling, "Well, what's the point if you're going to do it that way?" I thought the piece was another in a series of recent articles on how economical SOA can be - a topic tackled recently by eWeek's Channel Insider and David Linthicum for Software Development Times. The ZapThink article certainly starts out along those lines. In a nutshell, ZapThink noticed back in 2002 that traditional middleware-based integration generates "unpredictable spikes in cost" whenever business requirements change. They even drew a nifty Integration Cost Curve to explain this relationship.

In the past, there's been some buzz about how enterprise-class mashups could be used for data integration. This week, ZapThink's Ronald Schmelzer offered guidelines on how IT can shift from talking about mashups to actually supporting them. He also made this important point: Mashups are not a replacement for or just another form of data integration: For certain, the act of composition achieves the goal of integration, and the consumer-centric mashup is just an aspect of composition. However, data mashups intend to solve different problems than traditional data integration approaches, and in many ways, do not replace the need for or value of traditional data integration solutions." To do this, though, you're going to have add a data-service layer. In case you don't know, ZapThink is a SOA consultant group, so this is where SOA comes into play, according to Schmelzer. Essentially, you're creating data services that can be loosely coupled, rather than the traditional, tightly coupling of enterprise data integration. You're bringing the SOA style to your data, so users can mash it up.
