| description.long | An object-relational mapping library for Node.js that uses proven patterns (Data Mapper, Unit of Work, Identity Map) to provide type-safe database access with minimal boilerplate. Supports multiple SQL and NoSQL databases with features including schema versioning, entity lifecycle hooks, and flexible data loading strategies. | A query-building library for Node.js that makes it easy to work with relational databases using both high-level abstractions and raw SQL when needed. It supports schema relationships, type safety through TypeScript, and works across multiple database systems. |
