Ormar
Ormar is an asynchronous object-relational mapper for Python that integrates database persistence with data validation. It functions as a bridge between relational database management and application-level data structures, allowing developers to define database schemas that serve simultaneously as validation models.
The project distinguishes itself by using validation classes to enforce schema integrity, ensuring that all persisted records conform to defined types and structures. It supports complex relational associations, including one-to-many and many-to-many relationships, and provides event-driven lifecycle hooks that trigger custom logic during record state changes to maintain data consistency.
The library covers a broad range of database management capabilities, including non-blocking query execution and automated schema migration tools. It utilizes a low-level query builder to translate object methods into structured database operations, while providing command-line utilities to synchronize physical database versions with application code across different environments.
