Cache a database

Question

I have a problem to solve and at some point of it. It says this:

I decided to use a relational database to cache calculated data for the next calls.

What does the cache part means? Where is that data sorted? Is it saved in a temporal table? How can I access to that information?

Thanks in advance!!

Answer 1

"Cache calculated data" means the results of some resource-consuming calculations are stored in a database for faster future access without re-calculation. The data can be stored in one or several tables, it can be versioned or not, so particular implementation may vary.
