<P>

The Business layer (or middleware layer) incorporates the logic for encapsulating 
the business process. Within this layer it is the responsibility, 
from the Microsoft perspective, that COM and MTS (Microsoft 
Transaction Server) interact with other Distributed coordinated 
services to provide transactions for business "state" information. 
For example, while IIS and ASP deliver content COM objects either 
running with MTS or other middleware technologies, would provide 
the logic for managing the business process. 

<P>

Microsoft Transaction Server provides support for distributed 
transactions and the co-ordination of those transactions. It 
also supports the notion of packaging components and web 
applications together within the same solution to provide 
faster access and Just In Time activation for their component 
parts. 

<P>

MTS also provides a roles management system to enable a 
more "work flow" style approach to running the business 
components.

<P>

Microsoft also includes a Message Queue service. MSMQ aims 
to provide a queue and state management solution via a 
guaranteed delivery mechanism. The purpose of which is to 
enable designers to implement state machines and queues 
without repeat development. This frees developers from 
having to re-implement messaging technology for each 
solution.
