Last week, I reported on Ash Parikh's discussion on data being the missing link in SOA efforts. Companies are missing the effective establishment of data services that assure the information flowing through SOA-enabled applications is timely and accurate.
Dave Linthicum also zeros in on this challenge, observing that while plenty of smart people understand what SOA needs to do, the data focus is missing -- "and that is killing SOA." He notes that SOA and enterprise architects focus on the service definition, but don't pay enough attention to the data within the architecture.
In any project, there needs to be coordination between the SOA side of the house and the enterprise data management side.
