The Integration Repository is designed to help integrate Oracle ATG Web Commerce applications with remote systems. It assumes that your business maintains data on a remote system and you want to expose and possibly modify this data within your Oracle ATG Web Commerce application in the form of Oracle ATG Web Commerce repository items. There are several ways you can set up such an integration, depending on the demands of your Oracle ATG Web Commerce application and the characteristics of the remote system and the data maintained there. Here are four possible approaches for getting remote data. Which approach to choose depends on balancing your need for consistent data and best performance.
