relational database management system (RDBMS)

A relational database management system (RDBMS) is software that organizes data into structured tables with rows and columns, much like a spreadsheet. These tables store related information and can be linked through common fields, enabling efficient data retrieval, updates, and management. RDBMSs use tools like SQL (Structured Query Language) to efficiently query and manipulate data. They ensure data consistency, integrity, and security, making them suitable for handling complex, interconnected data in applications like banking, e-commerce, and enterprise systems.
