Can you describe the key characteristics of relational database management systems?

Relational database management systems (RDBMS) are characterized by the following key features:

• Tabular data structure: data is stored in tables (relations) consisting of rows and columns.

• SQL query language: used for defining, manipulating, and managing data.

• Data integrity: support for constraints (e.g., primary keys, foreign keys) to ensure data consistency.

• Transactions: support for atomic operations with ACID properties (atomicity, consistency, isolation, durability).

• Relationships between tables: ability to establish links between tables through keys, allowing modeling of complex data structures.

• Data independence: logical and physical data independence, enabling changes to storage structures without affecting applications.

These characteristics make relational DBMS a powerful tool for storing and processing structured data.
