Implementing Services for Message-Based Communication ppt

Implementing

Services for

Message-Based

Communication

Chapter 11

In n-tier architecture, the clients and servers can be placed at

distant locations. The server that implements business logic

can provide services to various clients. In such a scenario, it

is essential to ensure asynchronous communication. This

allows the client applications to send requests even if the

server is not available to process the requests immediately.

SQL Server 2005 allows you to implement this by using

service broker.

Service Broker is a feature provided by SQL Server that

provides a platform on which the services interact by

sending and receiving messages. Services are self-contained

components that provide a required functionality.

This chapter provides an overview of message-based

communication. Further, it explains how to implement

services for a message-based communication.
