COM+ is an extension of Component
Object Model (COM), Microsoft's strategic building
block approach for developing application programs. COM+ is both an
object-oriented programming architecture and a set of operating system
services. It adds to COM a new set of system services for application
components while they are running, such as notifying them of significant events
or ensuring they are authorized to run. COM+ is intended to provide a model
that makes it relatively easy to create business applications that work well
with the Microsoft Transaction Server (MTS) in a Windows NTŪ or subsequent
system.
Among the services provided
by COM+ are:
·
An event registry that allows components to publish the possibility of
an event and other components to subscribe to be notified when the event takes
place. For example, when a sales transaction is completed, it could trigger an
event that would allow other programs to be notified for subsequent processing.
·
The interception of designated system requests for the purpose of
ensuring security
·
The queues of asynchronously received requests for a service
