Overview of NOSQL Databases

Abstract

The proliferation of big data necessitates the business storing an increasing amount of data. The data in the enterprise's database must be accessible quickly. However, the Relational Database (RDB) is limited in its speed due to the join process. Therefore, numerous businesses have shifted to NoSQL databases, which can fulfill the need for rapid data access. Nonetheless, there are hundreds of NoSQL databases. It is critical to choose an appropriate NoSQL database for a particular business since this choice will affect the performance of the enterprise's operations. Four major types of NoSQL databases will be discussed in this thesis paper to determine their features and compare them to one another. Some ideas and examples are provided for selecting a suitable NoSQL database for various sectors and a comparison of NoSQL with RDBMS.
