Chapter 3. The Simplest Notification Application: Stock Quotes


IN THIS CHAPTER

  • The SQL-NS Application Model

  • Building the Stock Application's ADF

  • Specifying Other Parts of the Stock Application

  • Running the Stock Application

  • Inside the Running Application

  • What Has the SQL-NS Platform Provided?

  • Cleaning Up the Instance and Application

In this chapter, you'll see your first SQL-NS application: a stock notification service similar to those offered by many real-world stockbrokers. The application allows subscribers to enter subscriptions for stocks in which they are interested and notifies them when those stocks cross the price targets they specify.

Think of this chapter as a tour. My intent is simply to show you around the various facilities that the SQL-NS platform offers so that you get a feel for the application model and the process of coding to it.

We will look at code in this chapter, but simply for the purpose of understanding the concepts behind the application. A line-by-line explanation of the code at this stage would drown out the simpler picture that I'm trying to show.

Instead, I will gloss over (or in some cases, completely ignore) some parts of the code you will see; I'll just highlight those pieces of the code that illustrate particularly important parts of the application model. Subsequent chapters will cover the rest in detail.
