What is NoSQL and explain it?
NoSQL is an approach to database management that can accommodate a wide variety of data models, including key-value, document, columnar and graph formats. A NoSQL database generally means that it is non-relational, distributed, flexible and scalable.
Why is it called NoSQL?
When people use the term “NoSQL database,” they typically use it to refer to any non-relational database. Some say the term “NoSQL” stands for “non SQL” while others say it stands for “not only SQL.” Either way, most agree that NoSQL databases are databases that store data in a format other than relational tables.
What is the difference between DBMS and NoSQL?
NoSQL uses to store data in structured, semi-structured and unstructured forms. In regular DBMS, the data not be stored following the ACID. It creates an inconsistencies database. RDBMS are harder to construct and obey ACID (Atomicity, Consistency, Isolation, Durability).
What is the advantage of NoSQL?
When compared to relational databases, NoSQL databases are often more scalable and provide superior performance. In addition, the flexibility and ease of use of their data models can speed development in comparison to the relational model, especially in the cloud computing environment.
What is the difference between MySQL and NoSQL?
MySQL is a relational database that is based on tabular design whereas NoSQL is non-relational in nature with its document-based design. MySQL has established a database, covering huge IT market whereas NoSQL databases are the latest arrival, hence still gaining popularity among big IT giants.

What is NoSQL advantages and disadvantages?
NoSQL puts a scalability and performance first but when it comes to a consistency of the data NoSQL doesn’t take much consideration so it makes it little insecure as compared to the relational database e.g., in NoSQL databases if you enter same set of data again, it will take it without issuing any error whereas …
