The recommended architectural pattern for both is CDC-based streaming to a columnar OLAP layer (ClickHouse/Tinybird), keeping the operational database for transactions. Includes a practical Oracle-to-Postgres SQL translation table and notes on PL/SQL migration challenges. ## Full article daily.dev links to this article rather than hosting it.
