What is the best way to manage cross-engine database migrations?▼

The best way to manage cross-engine database migrations is using a unified reldb API that provides consistent DDL methods like createTable and dropTable, ensuring reliable schema evolution across SQLite, PostgreSQL, and MySQL.

Can I execute typed SQL queries with transactional guarantees across multiple database engines?▼

Yes, you can execute typed, parameterized SQL queries with end-to-end transactional guarantees across multiple database engines by utilizing a unified data access interface designed for backend services.

Does this unified database API support JSON operations and standardized error handling?▼

Yes, the unified database API supports JSON operations alongside standardized HaiResult-based error handling, providing a uniform developer experience and reliable data access across all supported engines.

How do I initialize reldb for cross-database data access in a backend service?▼

To initialize reldb for cross-database data access, install the library, configure it with your specific database engine settings, and start performing unified DDL, CRUD, and transaction operations through the provided interfaces.

Why should I use a unified API instead of engine-specific drivers for SQL and CRUD operations?▼

You should use a unified API instead of engine-specific drivers to eliminate boilerplate code, prevent syntax drift during DDL and CRUD operations, and maintain consistent transactional guarantees across SQLite, PostgreSQL, and MySQL.
