A requestor application connects to a webMethods Broker and sends a request for information about a customer (contained in a C# message) to a server application. Using information in the request message, the server application builds a query, which it executes against a customer database.

The server retrieves the query results containing the customer information, and maps the data to a C# reply message. The server then sends the reply to the requestor application. The requestor application processes the reply message, extracts the customer data, and sends the customer data to the console for viewing.
