Patterns for EAI/EII

Three basic patterns are used for the implementation of EAI and EII platforms:

  • Direct connection
  • Broker
  • Router

Direct connection represents the simplest type of interaction between two applications and is based on a 1: N topology, in other words, an individual point-to-point connection. It allows a pair of applications within an organization to communicate directly. Interactions between the source and the target applications can be as complex as necessary. Additional connection rules are defined for more complex point-to-point connections. Examples of connection rules include data mapping rules, security rules, and availability rules.

The direct connection pattern can be broken down into the following logical ...
