Messaging means the passing of data from one point to another. In BizTalk it
'normally' means a single XML message, but not all of the time.
A messages which has payload data, but also can have context data (recieved
file name is a good one). Not only can the message have payload data, along
with context data, but there can be multiple documents attached to a
message. HL7 is a good example of how the parser splits the MSH segment
(header) apart from the detail, both (or sometimes all three) xml documents
together. Email is a good example, you can have multiple message parts, one
that represents the body of the email, and other messages that would be
attachments.
Reeling back to the original question, Server A would send a message in a
variety of ways, to keep it simple, it drops a file off and BizTalk picks up
the file, the flat file parser converts it into an XML message and passes it
to the destination system, converting along the way, this message starts off
first as a flat file, then is converted to XML and then possbily back to a
flat file for importing into Server B. If Server B requires more information
from System A, it will send a new request message to System A, and will wait
for the response message and then continue on in the import.
Hope that this helps,

This must be the dumpiest question. I am new to the whole integration
concept.
I've heard alot that the heart of Biztalk is messaging. So can someone
please explain to me what does the message do? I've read a lot of
Biztalk white paper but I dont understand the basic yet. So say there
are 2 applications that store demographic information and there is a
need to integrate these 2 systems. If Server A sends a message to
Server B to do something, does this "message" contain the requests for
Server B to do something or Server A update a piece of information on
Server B on real-time?
Will be grateful if someone can please explain this to me....
Many thanks
Peddie
