Can you name the main types of requests used in databases or APIs?

The main types of requests used in databases and APIs include:

1. GET — request to retrieve data. For example, get a list of users.
2. POST — request to create a new record or resource.
3. PUT — request to fully update an existing record.
4. PATCH — request to partially update a record.
5. DELETE — request to delete a record.

In the context of SQL databases, the main request types are:

• SELECT — data retrieval from tables.
• INSERT — adding new records.
• UPDATE — updating existing records.
• DELETE — deleting records.

These requests allow interaction with data: creating, reading, updating, and deleting (CRUD).
