Rule Sets

Rule Sets are sets of rules that you define in a particular sequence. EAI Dispatch Service parses the input document using these rules in sequence until it finds a rule that matches the input.

Rules

Rules are individual entities in a rule set. Each rule consists of data transformations, search expression grammar, and zero or more rule transforms. You define rules by using search expression grammar to establish how you want an input message to be routed. For details, see Search Expression Grammar.

Data Transformation

A transform specifies how the intermediate output is going to be generated before it is dispatched to the service and the method you specified in the rule. For details, see Output Transformation.
