TIBCO: The Information Bus Company (Middleware)
In data - level Integration, changes propagated from dependent systems bypass the integrated application, so all inserts, updates, and deletes are done to data that the integrated application accesses.
UI level Integration ties integration logic to user interface code. UI - level integration is scripting or proxy - based. Scripting - based UI - level integration embeds integration code into the UI component events, common with client/server applications such as Power Builder or Vantive.
Application level integration uses the integrated applications' integration frameworks and APIs. Application interfaces let you invoke business logic to preserve data integrity. Integration API examples include Siebel's JAVA Data Beans and SAP's JCA (J2EE Connector Architecture).
