Caching

Caching is the process of storing frequently accessed data in a temporary storage location, called a cache, in order to quickly retrieve it without the need to query the original data source. This can improve the performance of an application by reducing the number of times a data source must be accessed.

There are several caching strategies:

• Refresh Ahead
• Write-Behind
• Write-through
• Cache Aside

Also, you can have the cache in several places, examples include:

• Client Caching
• CDN Caching
• Web Server Caching
• Database Caching
• Application Caching
