“RDBMS” stands for Relational Database Management System. It is a type of database management system that organizes data into structured tables, allowing for relationships between different data entities. This structure enables users to perform operations such as insertion, updating, retrieval, and deletion of data using a standard language known as SQL (Structured Query Language). RDBMSs support data integrity and facilitate concurrent access by multiple users, making them essential for applications requiring reliable data management, including e-commerce and enterprise resource planning.
