Detailed explanation-1: -Arguably the most important advantage of the RDBMS is its ability to hide the complexities of the relational model from the user. The RDBMS manages all of the physical details, while the user sees the relational database as a collection of tables in which data are stored.
Detailed explanation-2: -A relational database is a collection of information that organizes data in predefined relationships where data is stored in one or more tables (or “relations") of columns and rows, making it easy to see and understand how different data structures relate to each other.
Detailed explanation-3: -RDBMS stands for Relational DataBase Management Systems. It is basically a program that allows us to create, delete, and update a relational database. Relational Database is a database system that stores and retrieves data in a tabular format organized in the form of rows and columns.
Detailed explanation-4: -What is the Difference between DBMS and RDBMS? DBMS stands for Database Management System, and RDBMS is the acronym for the Relational Database Management system. In DBMS, the data is stored as a file, whereas in RDBMS, data is stored in the form of tables.
