Here’s the difference between SelectDB and Oracle. The comparison is based on pricing, deployment, business model, and other important factors.
SelectDB is a real-time data warehouse company established in January 2022, of which the founding team members are the active and core contributors from the Apache Doris open-source community. SelectDB has been largely contributing to the open-source community of Apache Doris. Meanwhile, it has developed its own commercial version based on the kernel of Apache Doris, offering enterprise out-of-the-box data warehouse services which could be realized on multi-cloud.
Oracle Autonomous Data Warehouse is a cloud data warehouse service that eliminates all the complexities of operating a data warehouse, securing data, and developing data-driven applications.

It includes tools for self-service data loading, data transformations, business models, automatic insights, and built-in converged database capabilities that enable simpler queries across multiple data types and machine learning analysis.
