This skill equips Claude with production-grade implementation patterns for interacting with various database systems using C#. It focuses on best practices for library selection, connection management, and parameter styling across diverse environments including modern DuckDB Parquet queries and legacy systems like Sage 1000 and DBISAM. By leveraging standardized wrappers and the ExecuteAndMap pattern, it ensures that database code is performant, null-safe, and easy to maintain while providing specialized guidance for PostgreSQL-specific features like native arrays and explicit type casting.
