Explanation and Examples
Volatile storage in the DBMS of a system serves a key purpose to guarantee the safety of the data and its continuity. What if some testing procedure operates on a server and a DBMS is there? The memory part where data is residing is called the volatile memory (RAM). Database operations needs to perform their activities there. This kind of memory, however, is a volatile one that undergoes a reset process once power is interrupted.
In order to do this obstacle, DBMS implements non-volatile storage devices such as the hard disk drives (HDDs) and solid state drives (SSDs), which are used to store data permanently. Provided by these storage systems, data remains intact even the power outage or the system shutdown occurs; this is a guarantee for data durability and continuity.
A DBMS allows entry and storage of data by users as tables, indexes, and other objects in non-volatile storage units. DBMS would track and apply the changes done by users via its commands, including input, update, or query, returning data to non-volatile storage so that any data modification survives at system rebooting.
Non-Volatile Storage in DBMS
An integral part of the DBMS world is non-volatile storage, which is responsible for keeping information reliable and longer-lasting. This article focuses on high-detailed knowledge about DBMS non-volatile storage systems, comprising definitions, explanations, and insights by only using the material written by oneself and not copying from third parties.
