Are we there yet? Are we there yet? Queries that poll a database looking for changes can waste tremendous amounts of network bandwidth, CPU, and other precious database server resources. By changing the structure of your SQL client to use query notifications rather than polling, you can reduce computational load on both the client and the server. We’ll review how you can use query notifications from C# or VB.NET to receive notifications from Microsoft SQL Server. We’ll compare polling, database triggers, and query notifications, with respect to speed, reliability, and ease of implementation in a software bug tracking system.

Next, we’ll examine a case study of how these types of notifications can be implemented in an automotive assembly plant. The Toledo North and South Assembly Plants produce the Jeep Cherokee and Wrangler, respectively, and we’ll review a video explaining the assembly process at these plants with a special emphasis on some of the computer systems driving them. Given your newfound knowledge of query notifications, you’ll easily be able to understand why speed and reliability are so important in this environment. Examples of notifications include determining the positions of vehicles on the production line with RF-ID readers and real-time detection of production line failures.
