Relational Database Management System (RDBMS)

An RDBMS (Relational Database Management System) stores data in a structured format using tables.

• A table (made up of rows and columns) represents a data type
• Rows within the table represent records (instances) of that data type
• Columns represent the fields or attributes of the data type

SQL is used as a language to create, modify, and query the data.

Examples of popular RDBMS systems:

• Oracle
• MySQL
• Microsoft SQL Server
• PostgreSQL
