RDBMS (Relational Database Management Systems)

A Relational Database Management System (RDBMS) is software that stores and manages data in a structured way using tables, which are similar to spreadsheets. Each table consists of rows and columns, where rows represent individual records and columns represent attributes of those records. RDBMS allows users to easily access, update, and manage large amounts of data while ensuring data integrity and relationships between different data sets. It uses a language called SQL (Structured Query Language) for querying and managing the information. Popular examples include MySQL, PostgreSQL, and Microsoft SQL Server.
