Nosql - A solution for handling big data

Abstract

The data produced nowadays is the Big data which is unstructured, semi-structured or structured in nature. It is difficult for SQL to handle such large amount of data with varied forms so NoSQL was introduced which gives many advantages over SQL. It is a schema less database which allows horizontal scaling, scalability and distributed framework. SQL is based on ACID properties (Atomicity, Consistency, Isolation, Durability) whereas NoSQL is based on BASE (Basic Availability, Soft state, Eventual consistency). This paper introduces the concepts of NoSQL, advantages of NoSQL over SQL, different types of NoSQL databases with special reference to the document store database, MongoDB. It explains in detail about the MongoDB and then experimentally evaluates the performance of the queries executed in SQL and NoSQL (MongoDB). The experiment conducted shows that NoSQL queries are executed faster as compared to SQL queries and can also handle huge amount of unstructured data very effortlessly and easily.
