The different levels of caching that can be implemented with a database are as follows:

• Caching at database level: When we cache at the database level, we usually utilize the built-in functionality of the database, which caches the datasets that are being frequently used by maintaining the query caches.
• Caching at block level: Caching at the block level happens at the application level, where we cache the data fetched by the ORM layer into a memory-based data store so as to avoid running a database query every time a certain result is asked for.
• Caching at the user level: When caching at the user level, the non-security-critical data is cached at the client side through the use of session cookies or local storage.
