Defining a context

A context is a relationship between two or more business events that are processed by Decision Server Events. A context can also track action occurrences.

About this task

A context describes the conditions that the rules in an event project use to evaluate and correlate events. For example, if an event project includes a context with four events that involve credit card processing, and the context ID is the vendor number, then the rules evaluate the event information based on that specific vendor. Therefore, if a rule says past occurrences of new customer within 1 day is more than 100, this evaluation indicates that the current vendor added more than 100 new customers in the past 24 hours.

You can complete the following tasks to define a context. The tasks are described in more detail in the related topics.

Procedure

Add a context ID to the system context, or create a context definition.
Associate a rule with a context definition by editing the event rule and selecting the Change event option.
Modify the conditions in the context definition to control how events participate in the context.
Important: If you created an event project that includes an event flow in a previous version of Decision Server Events, the event flow is upgraded to a context definition when you import the event project into V8.0.1. The events in this context definition do not include associated context IDs. Instead, the context IDs are specified in the rules or rule groups in the imported event project.
