NoSQL is a movement promoting a loosely defined class of non-relational data stores that break with a long history of relational databases and ACID guarantees.


You need to ensure ACID compliance (atomicity, consistency, isolation, durability): ACID compliance reduces anomalies and protects the integrity of your database by prescribing exactly how transactions interact with the database. Generally, NoSQL databases sacrifice ACID compliance for flexibility and processing speed, but for many e-commerce

Up till then, transactions were usually committed on one server, then replicated to the rest of the cluster in an “eventually consistent” manner. BergDB is a light-weight, open-source, NoSQL database designed from the start to run ACID transactions. Actually, BergDB is "more" ACID than most SQL databases in the sense that the only way to change the state of the database is to run ACID transactions with the highest isolation level (SQL term: "serializable"). 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. A NoSQL (originally referring to "non- SQL " or "non-relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. NOSQL databases and that of ACID in relational databases.

The ACID properties of a database are Atomicity, Consistency, Isolation and Durability. ‌ Atomicity — An “all or nothing” approach. If any statement in the transaction fails, the entire transaction is rolled back. Consistency — The transaction must meet all protocols defined by the system.

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.) NoSQL databases are purpose built for specific data models and have flexible schemas for building modern applications.

I'm new to NoSQL and have been a user of relational databases for many years. It's a very strange concept for me to imagine a database that doesn't have ACID 

NoSQL-databaser kallas även ”icke-relationella”, ”NoSQL DB” och ”icke-SQL” för att framhäva det faktum att de kan hantera enorma volymer snabbt föränderliga, ostrukturerade data på andra sätt än en relationsdatabas (SQL) med rader och tabeller. NoSQL platforms group data based on a user-defined or system-generated key and assign the responsibility of interacting with data partitions to different nodes in a cluster.
