The document describes ITC Infotech's EASI (Eloqua and Siebel Integration) product, which integrates Eloqua marketing automation software with Siebel CRM. EASI allows marketing segments created in Siebel to be exported to Eloqua for campaign execution. It also synchronizes contact data and campaign responses between the systems. The integration flows include loading Siebel contacts and segments into Eloqua, updating contacts in real time, and creating Siebel activities from Eloqua responses. EASI uses custom workflows, APIs, and a cloud connector to provide end-to-end integration between Siebel on-premise and Eloqua.
