Relational Database Management System
A Relational Database Management System (RDBMS) is a software system that manages relational databases. It allows users to create, update, and administer databases, as well as provide a variety of tools for managing data. RDBMSs are based on the relational model, which organizes data into one or more tables (or relations) of columns and rows, with a unique key identifying each row. The RDBMS provides a set of operations to manipulate the data stored in the tables, including querying, updating, and deleting data. It also enforces data integrity constraints, such as ensuring that each row has a unique key and that foreign key relationships between tables are maintained. Examples of RDBMSs include MySQL, Oracle, and Microsoft SQL Server.
