Enterprise Application Integration (EAI)
The linking and sharing of multiple business applications and data, including extensions to business partners, through the use of application-to-application modules, object middleware and message brokering, or multitier application server platforms. Motivations for EAI include the need to rapidly implement Web-based projects, the need to link to legacy data, and the need to forge links to different systems acquired through corporate mergers and acquisitions.
