Hi @gauron, sure ODBC is an old standard but with huge survival qualities. Early in my career (circa 2000) I worked with it and found direct ODBC usage cumbersome, so I typically used ADO over an ODBC driver instead. I’ve also wondered why HDB++ doesn’t use an ORM layer, but in practice that would hide database-specific strengths (e.g., Timescale hypertables), so the choice to write several DB backends makes probably sense. What’s your specific use case?
