What is a concern with using an in-memory database?

An in-memory database keeps all its data in the random access memory (RAM) of a computer. Only the main memory is accessed when querying data. This allows for faster access of that data than a disk-based system. The downside is the volatility of RAM. The data is lost when an in-memory database crashes.

What is the difference between data and memory?

Data is stored both temporarily and permanently. Memory is faster than storage. Memory can access data and information instantly. Storage cannot access or modify data as fast as the memory.
