Are databases stored in RAM?

Where is database data stored?

Inside a database, data is stored into tables. This is why tables have been created. Tables are the simplest objects (structures) for data storage that exist in a database. For example, the picture above is a screenshot of a table that has stored general information about some cars.

Are databases stored on disk?

Database tables and indexes may be stored on disk in one of a number of forms, including ordered/unordered flat files, ISAM, heap files, hash buckets, or B+ trees. Each form has its own particular advantages and disadvantages. The most commonly used forms are B-trees and ISAM.

Which type of memory is widely used for databases?

An in-memory database (IMDB, or main memory database system (MMDB) or memory resident database) is a database management system that primarily relies on main memory for computer data storage.

Is data the same as RAM?

RAM is volatile, meaning the information that's put in there disappears when the power is turned off or when the computer is reset. Storage is different—it's persistent. Data stays written on the disk until it's erased or until the storage medium fails (more on that later).
