Primavera Gateway is a three-tier system that includes web, business, and database tiers. Each of these tiers provide specific functions to synchronize data between a source application and a destination application. The system architecture diagram below describes how these three tiers work together to synchronize data between applications when external providers reside outside the Gateway framework. The Gateway framework is a web application that is deployed on a WebLogic application server and provides the following functions:
- Provides orchestration of the business flow steps within Primavera Gateway.
- Provides job scheduling services.
External providers enable you to create, maintain and update providers outside Gateway, but allow you to use these providers within Gateway framework as-needed, and on-demand. For more details on developing external providers, download the Customization.SDK from the Help menu of the Gateway user interface.
Note: You can also set up integration scenarios between an external provider connecting with a provider delivered in Gateway. In this instance, the system architecture will be a hybrid scenario of the two system architecture diagrams.
