In computer science, ACID is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter

14 Dec 2020 [7][8], Database systems designed with traditional ACID guarantees in mind such as RDBMS choose consistency over availability, whereas 

That is, all the changes are performed, or none of them are. ACID is an acronym describing not the database itself but the features of individual database transactions run through the system. In simple terms, all transactions of an ACID compliant database system comply with the following requirements. Atomicity: Each database transaction must completely succeed or completely fail.

In database systems, ACID (Atomicity, Consistency, Isolation, Durability) refers to a standard set of properties that guarantee database transactions are processed reliably. ACID is especially concerned with how a database recovers from any failure that might occur while processing a transaction. The ACID model of database design is one of the oldest and most important concepts of database theory. It sets forward four goals that every database management system must strive to achieve: atomicity, consistency, isolation, and durability.

A database transaction is any operation performed within a database, such as creating a new record or updating data within one. Changes made within a database need to be performed with care to ensure the data within doesn’t become corrupted.

24 Jan 2017 Graph database technology contains some technological features inherent to traditional databases, e.g. ACID properties and availability. Use 

It includes four goals that every database management system must try to achieve: atomicity, consistency, isolation and durability. If the database does not meet these four goals, it is not considered reliable.

Therefore, the ACID property of DBMS plays a vital role in maintaining the consistency and availability of data in the database. Thus, it was a precise introduction of ACID properties in DBMS. We have discussed these properties in the transaction section also.

The key ACID guarantee is that it provides a safe environment in which to operate on your data.
