What types of database operations have you implemented in your projects?

In database projects, the following types of operations are usually implemented:

• CRUD (Create, Read, Update, Delete): creating, reading, updating, and deleting data.
• Transactions: executing multiple operations as a single unit with the ability to rollback on errors.
• Query optimization: indexing, using prepared statements.
• Backup and recovery: creating backups and restoring data.
• Monitoring and logging: tracking performance and errors.

For example, a project might implement a REST API for working with the database, where:

• POST — create a record;
• GET — retrieve data;
• PUT/PATCH — update;
• DELETE — delete.

An ORM is also often used to simplify database interactions.
