Cross-database transactions are managed using transactional wrappers that coordinate repository operations. This ensures reliable commits and automatic rollbacks during exceptions, maintaining data consistency across SQLite, PostgreSQL, and MySQL.
The BaseReldbCrudRepository simplifies relational database CRUD operations by providing a business repository pattern. It automatically handles timestamping and maps boolean and JSON fields, reducing manual data conversion logic.
Structuring data-layer modules for multiple SQL databases is best achieved by extending the BaseReldbCrudRepository. This approach enforces consistent API results and abstracts DDL, CRUD, and transaction handling for production-grade repositories.
Pagination and structured error handling are fully supported for relational database queries. The Skill enforces a consistent HaiResult-based API and provides specific HaiReldbError branches for precise error handling during data access.
