Reverse ETL is the process of automating the flow of data from a database or data warehouse back out to external systems and applications, closing the loop that ETL/ELT starts, allowing users to easily access valuable data stored in the data warehouse. The rise in popularity of Reverse ETL stems from modern organizations' increasing usage and consumption of data across dozens of SaaS applications and tools, leading to a need for employees to extract and enrich their relevant data within their preferred tool. Organizations can use Reverse ETL to operationalize their data, such as augmenting CRM data with customer data or automating connectivity with Accounts Receivable data, reducing manual work and democratizing operational data, enabling informed business decisions.
