3) Overview of NoSQL:

In the era of Big Data, the emergence of NoSQL has revolutionized how we handle unstructured and semi-structured data. NoSQL stands for “not only SQL” and is a type of non-relational database that manages data differently compared to the structured data management provided by SQL.

NoSQL databases are designed to handle massive volumes of data, making them ideal for modern web-scale applications that require real-time data processing. Definition and Purpose of NoSQL:

NoSQL databases exist to handle unstructured and semi-structured data, a type of data that does not fit into traditional SQL database structures.

NoSQL databases are designed to handle various data formats such as documents, graphs, and key-value pairs. Furthermore, these databases usually run on distributed systems, which provide scalability and fault tolerance.

NoSQL databases are commonly used in environments where speed and flexibility are important, making them ideal for applications such as social media and mobile apps. Development of NoSQL vs.

SQL:

The relational database era, which began in the 1970s, marked the beginning of SQL. SQL was used overwhelmingly in structured data management until the emergence of NoSQL in the latter part of the 20th century.

Although the term NoSQL was not coined until the 2000s, its development had already begun in the late 1990s. The emergence of NoSQL was driven by a need for more flexibility in handling different data types, particularly Big Data and real-time web applications.

Comparison of SQL vs. NoSQL:
