Pat Helland, architect at Microsoft, lets you in on the service oriented architectures are essential. "People need to drive themselves toward SOA."
Pat also has a blog where he responds to Channel9 viewer mail.
I have spent the last 6 years preaching this kind of thing to my coworkers at first and my clients now. Even before it had a name or at least before its name was known to me. In healthcare there are tremendous repositories of data that hold information encased
within the confines of systems that were developed in Mesozoic times. Our firm has spend the past two years building on application paradigms that broke down those walls not by replacing those systems but by augmenting them with mechanisms for communicating
their contents and meaning to other systems. In many ways our use of the .NET development tools and processes has provided the glue if you will to further that ideal.
In the end we have processes and services in place that allow our clients to use what they are familiar with but to then have access to concatenations of relevant information from disparate systems. Its powerful stuff especially for folks used to working in
the dark and relying on other to provide the light.
What was that about idempotence?
Very well said Pat, to trim and shim, but we still have a long way to go with today’s SOA implementations. Think security, transactions etc.
