While the “X” of X database typically expresses the structure in which data is stored, ACID is a database model: a set of properties describing how changes are made within a database. The term ACID (Atomicity, Consistency, Isolation, Durability) describes rules and properties for carrying out transactions in database management systems (DBMS). If the transaction complies with the ACID principle, the information in the database systems is considered reliable and consistent. What are the ACID Database Properties? The ACID properties define SQL database key properties to ensure consistent, safe and robust database modification when saved. ACID is an acronym that helps to remember the fundamental principles of a transnational system. ACID stands for Atomic, Consistent, Isolation, and Durability.

Brand Manager & Developer: Aither Entertainment Limited In this part-2 remaining three explained-Consistency-Isolation -Durability In the NoSQL database world, ACID transactions are less fashionable as some databases have loosened the requirements for immediate consistency, data freshness and accuracy in order to gain other benefits, like scale and resilience. (Notably, the .NET-based RavenDB has bucked the trend among aggregate stores in supporting ACID transactions.) A database without transactions is… well, not much of a database, and as far as transactions are concerned - ACID is the gold standard. ACID document databases are widely accepted as a key player in crunching today’s masses of complex data, and RavenDB has been standing tall for over a decade now in guaranteeing ACID without sacrificing performance.
