It helped me analyse large-scale transaction data for finance clients, detect risk and fraud patterns using joins and window functions, and produce clear explanations and audit-ready insights. Review collected by and hosted on G2.com.

Debugging complete, long SQL queries is awkward, especially when you get into complex branching logic and custom algorithms. Portability also feels limited, and it’s harder to unit test compared to application code. On top of that, graph-based fraud rings, real-time scoring, model experimentation, and advanced feature engineering all feel lacking in SQL. Review collected by and hosted on G2.com.
