A Relational Database consists of a Collection of Organized tables with related data.
- RDBMS (Relational Database Management Systems) are databases that consists of organized tables that have an established relationship with each other. Since the information in tables is linked, it becomes very easy to retrieve particular records from tables consisting of thousands of rows.
- The programming interface in these databases is provided by SQL(Structured Query Language).
- In an RDBMS, the tables have a unique and Not Null column called as the Primary Key of the table. The PK on table references other column/columns in other tables, enforcing a referential integrity, called as the Foreign key thereby creating a relationship between two tables.
- Relational databases are highly scalable i.e. new rows can be added to tables without modifying the existing rows.
