These are known by the amusing backronym “BASE”, or “Basically Available, Soft State, Eventual Consistency”. While these are alternatives to ACID, the words “available” and “consistency” refer to the same properties as the CAP theorem, which lets you know these guarantees apply specifically to distributed databases.
Does no SQL support ACID properties?
NoSQL databases do not need a fixed table structure and does not provide a full ACID support. It provides eventually consistency, which means that data will be consistent over a period of time (Orend, 2010).
Do all NoSQL databases implement ACID properties?
Durability means the changes of the transaction are saved. It remains there even if power is turned off. Every relational database such as MySQL, postgresql, oracle and microsoft sql guarantees ACID properties of transaction.
Can NoSQL be ACID?

Why MongoDB is not ACID?
At its core, MongoDB is a document database and — almost by default — these kind of databases aren’t ACID compliant, especially when it comes to multi-document transactions (at the document level, MongoDB already supports ACID transactions).
How do NoSQL databases scale horizontally?
Scalability. … In contrast, NoSQL databases are horizontally scalable, which means that they can handle increased traffic simply by adding more servers to the database. NoSQL databases have the ability to become larger and much more powerful, making them the preferred choice for large or constantly evolving data sets.
Which database supports fully serializable ACID transactions?

What is the difference between SQL and NoSQL database?
SQL databases are table-based, while NoSQL databases are document, key-value, graph, or wide-column stores. SQL databases are better for multi-row transactions, while NoSQL is better for unstructured data like documents or JSON.
Is Cassandra an ACID?
Cassandra, ACID and BASE
While it does support other ACID-like features, such as strong consistency (using CL=ALL), compare-and-set updates with Lightweight Transactions, atomicity and isolation on the row-level, and has a durable writes option, it is inaccurate to describe Cassandra as an ACID-compliant database.
Is NoSQL good for transactions?
