Database Caching

Database caching is a method to temporarily store frequently accessed data in a high-speed storage area, like a cache memory, to reduce the time it takes to retrieve information. When a user requests data, the system first checks the cache; if the data is there (a cache hit), it’s delivered quickly. If not (a cache miss), the system fetches it from the slower primary database, then stores a copy in the cache for future requests. This process improves performance by minimizing access to the slower database, making data retrieval faster and more efficient.
