Immutable Database: What it is, How it Works, Requirements & Challenges (2022)

What is Immutable Data?

Immutable data refers to information stored within a database where any change or deletion cannot take place. It allows storing previous data points in contrast to mutable databases where information is overwritten with new additions. It is advantageous in the event of any data audit as tracking specific parts is more convenient with immutable data. By definition, “An immutable database stores all immutable data and is built with a reliable, decentralized, and secure infrastructure accessible only to parties involved.”

How Does an Immutable Database Work?

Unlike the functioning of a mutable database, an immutable database creates logs for all information. Whenever a new data entry is made, separate logs are created for the addition. No rewriting is taking place, and data can be traced back to different points when needed. There is no data loss that users had previously stored within the database. techiesin
