in MQSeries are binary data while the messages in ESB
are XML data. Those messages are, to me, at different
levels of inter software communication.
I hear people say they are using SOA becase there are
XML messages passing around. XML has been around for
a long time but SOA is relative new. SOA is more than
passing XML messages. There maybe minimum
requirements in an architecture to be called SOA. So
how to tell a SW architecture that is SOA or not?
