9 Many industries, including education, health care, and commerce, have used relational databases for decades. SQL databases are designed to effectively manage structured data. The ACID features of databases are used to manage data consistency and integrity. Physical database techniques improve the functionality of relational databases. Tablespaces are one of the physical database strategies used by Oracle SQL (sometimes known as subfolders). The purpose of tablespaces is to store data logically in separate files. In recent years, several businesses have generated enormous volumes of unstructured and semi-structured data (videos, photographs, blogs, etc.). This volume of information exceeds the capacity of SQL databases. NoSQL databases are used to manage and analyze massive amounts of data. Differentiate RDBMS from NoSQL.

- B. From the last decades, organizations of various nature such as education, health, businesses, among others use Relational databases. Structured Query Language (SQL) databases are designed to manage structured data and show tremendous performance. Atomicity, Consistency, Isolation, and Durability (ACID) property of relational databases is leveraged on to manage the integrity and consistency of data. Physical database techniques are harness to improve relational databases performance. Tablespaces also called subfolder is among the physical database mechanisms used by Oracle SQL database. Tablespaces are used to logically store data in separate data files. In recent times, enormous and diverse nature (unstructured and semi structured) of data is produced by different organizations i.e. videos, images, blogs etc. The SQL databases do not handle this large amount of data efficiently. NoSQL databases are rather used to process and analyze the huge data efficiently.
