☂️Reverse ETL: what it is and how to use it
Reverse ETL is the process of copying data from a data warehouse to operating systems, including SaaS for marketing, sales, and support. This allows any team of professionals, from salespeople to engineers, to access the data they need on the systems they use. There are 3 main use cases for reverse ETL:
• Operational analytics - providing insights to business teams in their normal workflows and tools to make data-driven decisions
• Data Automation — Automate ad hoc requests for data from other teams, for example, when financiers request product usage data for billing
• personalization of interaction with customers in different applications
