To integrate Domino data with an ERP system application, development teams require two things: a basic understanding of the system and applications they are connecting to, and Lotus enterprise integration tools and connectors know-how. The purpose of this article is to help with both, by way of a PeopleSoft example. First, you learn the basics of the PeopleSoft application development environment and how PeopleSoft creates and executes business processes. Then, you learn how to integrate Domino with PeopleSoft at the application level, using the new Domino Connectors for PeopleSoft 7.0 and PeopleSoft 7.5 together with a forms-based integration tool, the Lotus Enterprise Integrator (LEI). The article includes step-by-step examples that should help jump start your efforts to build Domino applications that can either update data or request information from an ERP system.
