This trade-off allows for high availability and fault tolerance, as the system can continue operating even in the presence of network partitions or node failures. In addition, another feature of NoSQL databases is the “eventual consistency”, which means preferring availability and partition tolerance over strict data consistency. NoSQL databases distribute data across multiple nodes in a cluster, and as a result, they can accommodate increased data and user demands and parallel processing. These databases are designed to handle large volumes of data and high traffic loads, making them highly scalable horizontally. Scalability is another crucial characteristic of NoSQL databases. This flexibility eliminates costly schema transitions and allows for rapid prototyping and reuse. NoSQL databases offer a variety of structures, making them suitable when data models are evolving or when dealing with unstructured or semi-structured data. The distinctive feature of NoSQL databases is the flexible schema, which allows for flexible and dynamic data structuring. Lastly, durability assures that once a transaction has been recorded, it will continue to exist even if the system fails. Isolation confirms that simultaneous operations aren’t in conflict with one another. The consistency of the database guarantees that it is in a legitimate state both before and after a transaction. Atomicity ensures that a transaction is handled as a single unit, either completely completed or entirely reversed in the event of failure. SQL allows developers to use a single syntax for constructing queries, performing complex joins, and modifying data, along with a plethora of tools, libraries, and frameworks that facilitate data management, reporting, and analysis.įurthermore, SQL databases provide the ACID attributes (Atomicity, Consistency, Isolation, and Durability), which assure data integrity and transactional trustworthiness. In addition, SQL databases benefit from the widespread adoption and support of the SQL language. This key feature assures data consistency and enables fast searching and indexing. A schema describes the database’s structure, including tables, columns, data types, and table relationships. The adoption of a schema is the initial characteristic of an SQL database.
