This document discusses integrating Eloqua marketing automation with CRM systems like Oracle Sales Cloud. It describes how Eloqua allows two-way synchronization between its database and a CRM, capturing data from marketing activities and routing leads to sales. The key methods of syncing data between Eloqua and a CRM are inbound and outbound data flows. Inbound flows pull new/updated CRM records into Eloqua, while outbound pushes new Eloqua records to the CRM. Common ways to integrate the platforms are via native connectors, the Eloqua AppCloud, SOAP API, or flat file integration.
