| description.long | Alembic is an open-source database migrations tool that provides transactional DDL support, auto-generation of migration scripts, and non-linear versioning with dependency-graph structure for managing database schema changes. | 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. |
