difference between DBMS and RDBMS

A DBMS (Database Management System) is a system that allows you to store and manage data. It includes software that helps you store, organize and manage data. An RDBMS (Relational Database Management System) is a type of DBMS that uses relationships between data items. For example, if you have a database of students in your school, you can use a DBMS to store their names, grades and contact information. With an RDBMS, you can go one step further and create relationships between the data. For example, you can create a relationship between a student’s grade level and their teacher, or their parents’ contact information. Think of a DBMS like a filing cabinet, and an RDBMS like a filing cabinet with tabs that let you quickly see which files are in each folder. It’s a way to organize data so that it’s easier to find and use. Fun Fact: The first RDBMS was created in 1970 by an IBM researcher named Edgar F. Codd.
