Usage Models

When looking at your requirements, you should understand how you intend to use Siebel Financial Services EAI's integration capabilities. You need to determine how the integration will behave and under what circumstances. In other words, in what way are you planning to use this integration? This is referred to as the usage model.

There are two basic usage models, real time and batch, as shown in Figure 8. Batch mode has a single mode, and real time has two modes, either tightly-coupled or loosely-coupled. To help you determine the appropriate usage model, ask yourself the following questions.

• How do I plan to integrate Siebel Financial Services applications with other applications?
• Do I want to do it in real-time or in batch mode?
• If I want to do it in real-time, do I want the solution to be tightly-coupled or loosely-coupled?
