Can cache libraries replace databases?

Can cache libraries really replace databases in applications?

Cache libraries can enhance performance by storing frequently accessed data, but they don't fully replace databases.

What are the main differences between cache libraries and databases?

Cache libraries are designed for speed and temporary storage, while databases provide persistent storage and complex querying.

In what scenarios would I use a cache library instead of a database?

Use a cache library for high-speed access to data that doesn't need to be stored permanently, like session data.

Can I use both cache libraries and databases together?

Absolutely! Many applications use both to optimize performance and ensure data persistence.
