Consumer - A component that takes messages from the queue and processes them.If there are several queues, it is much more difficult but more flexible sometimes. If we use only one queue, it is much easier. Message Queue - A FIFO queue that holds queue messages until they are processed.Messages also contain a number of additional settings (see Message settings). When the message comes up to a consumer, its structure is validated, then passed to a message processor. Messages are validated and sent by a message producer and put to the “tail” of the message queue. Message - An information message which contains a message topic that indicates which message processor(s) will process it and a message body - an array of parameters required for the processing, for example, an entity id or a channel name.Supplementary information not covered in the body of the Message Queuing documentation. Technical terms used in the Message Queuing documentation.

MSMQ is also available with independent client functionality on computers running Windows CE 3.0. MSMQ 3.0 can be deployed on computers running Microsoft Windows and members of the Windows Server family. NET Framework offers a set of managed Message Queuing objects. This allows applications to be developed for the Internet as well, including both server-side (Internet Information Server) and client-side (Internet Explorer) applications. NET, Borland Delphi, and Powersoft Powerbuilder. Applications can be built in any of the popular development environments: for example, Microsoft® Visual Basic®, Visual Basic® Scripting Edition, Visual C++®, Visual Studio®. Message Queuing applications can be developed using C++ APIs or COM objects. With Message Queuing, the loose coupling between systems makes upgrading individual systems simpler. Using a workflow-agent architecture also minimizes the impact of changes in one system on the other systems. A typical design pattern is to implement an agent to interact with each system.
Workflow: Message Queuing makes it easy to create a workflow that updates each system. Outside sales: for example, sales automation applications for traveling sales representatives. Mission-critical financial services: for example, electronic commerce.Įmbedded and hand-held applications: for example, underlying communications to and from embedded devices that route baggage through airports by means of an automatic baggage system. The following list shows several places where Message Queuing can be used. It can be used to implement solutions to both asynchronous and synchronous scenarios requiring high performance. Message Queuing provides guaranteed message delivery, efficient routing, security, and priority-based messaging. The following illustration shows how a queue can hold messages that are generated by multiple sending applications and read by multiple receiving applications. Applications send messages to queues and read messages from queues. Message Queuing (MSMQ) technology enables applications running at different times to communicate across heterogeneous networks and systems that may be temporarily offline.
