Crystal Data Source Projects
Now that you have seen the extensive power of the Crystal Data Source interface implemented inside a Visual Basic class, you can begin to consider the extensive possibilities for its use. Many computer based operations produce continuous streams of data in real-time. In your own work, you may encounter needs for gathering data from process control systems, data acquisition applications, or computer-based instrumentation.
In these kinds of applications, data is usually gathered and stored for later analysis. Systems running in real-time, however, may need real-time monitoring and reporting. With objects that implement the Crystal Data Source interface, you can gather and move through data as it is generated, then produce up to the instant analysis through reports.
Programmer's building n-tier applications that operate across a network may often find themselves designing business objects and other business rules components. By implementing the Crystal Data Source interface in business object components, you can design reports that produce real-time information about data traveling across the network. Even Microsoft Transaction Server components can implement a fully functional ActiveX data source for reporting. Crystal Data Source takes your applications from runtime to real time.
