BizTalk Pattern: Mapping Reference Data
What is reference data? Typically by reference data we mean an attribute of an object within a system that is restricted to a specific list of values. In integration scenarios when you are passing a message from one system to another these lists of reference data are different between the systems. This means if you have a product type id or value from System A there will usually need to be some kind of mapping required to translate the value or id to an equivalent value that System B will understand. ......

This logging usually masks the fact that the code was very buggy during development and also probably has no unit tests or has very low code ......

BizTalk Anti Pattern: The plug and play SOA
Name: The Plug and Play SOA Description: I have seen occasions where BizTalk has been stuck between two systems simply because it is perceived to decouple them. One case was where System A called an API on System B which was exposed as a set of web services. All BizTalk was planned to do was accept the web service call from System A and forward it to System B. Some of the design thoughts included: Thought Other consideration "We can replace System B and System A is not affected" Well yes but the ......
