The architecture of Biztalk is designed to make the tasks involved in managing messaging easier.
At it's most fundamental messaging has been described as the exchange of structured data.
Biztalk uses the term orchestration to describe how it controls the sequencing of messages.
Planely a business process could and typically does involve the exchange of messages.
At one level Biztalk server itself can be seen as an transformation engine, transforming XML documents from one structure to another.
Documents go in one end, get transformed, and come out the other end, in this way they can be seen as messages that are restructured and updated as part of a business, moving in sequences that reflect a particular process.
When a message arrives at a location (url) it triggers a listner and conceptually the listner is responsible for placing the message in receive pipeline.
