Episode 32: Service Oriented Architecture, Pt.2a

In this, as well as in the next episode Eberhard and Markus
continue their discussion about SOA (the episode got too long, so
we had to split it into two ... SOA 2a and SOA 2b). In this
episode, we talk about the various perspectives on SOA (CBD, EAI,
BPM), about fundamental requirements towards an SOA, and we discuss
the role of models in defining sustainable architectures. We also
discuss how a programming model based on the described approach
typically looks like. We then discuss a number of issues any
large-scale SOA faces (and for which the SOA paradigm does not
really provide an out-of-the-box solution: In this episode we
discuss data type ownership and (weak) typing of data types.
