Message and Data Flow
The following figure shows the C# client's message and data flow.
The numbers in the figure correspond to the sequence of messaging steps described below:
Step
Description
1
The requestor application builds a C# message containing a lookup request for customer information.
2
The requestor sends a message to the server application. The message contains the information needed to lookup a customer record.
3
The message selector ensures that only messages from the selected record are passed to the server.
4
The server receives the message requesting detailed customer information (the complete customer record).
5
The server parses the request message, builds a database query, and executes the database query against a simple in-memory database containing customer records.
6
The server maps the query results to a reply message and links the reply message to the original request.
7
The server sends the reply back to the requestor application.
8
The requestor extracts the customer data from the reply.
9
The requestor sends the customer data to the console.
