Correct Answer - Option 2 : RDBMS

Relational Data Base:

• A relational database is a collection of data items with pre-defined relationships between them.
• These items are organized as a set of tables with columns and rows.
• Tables are used to hold information about the objects to be represented in the database.
• Each column in a table holds a certain kind of data and a field stores the actual value of an attribute.
• The rows in the table represent a collection of related values of one object or entity.
• Each row in a table could be marked with a unique identifier called a primary key, and rows among multiple tables can be made related using foreign keys.
• This data can be accessed in many different ways without reorganizing the database tables themselves.
• Examples: Popular examples of standard relational databases include Microsoft Access, Microsoft SQL Server, Oracle Database, MySQL, and IBM DB2. Cloud relational databases include Amazon Relational Database Service (RDS), Google Cloud SQL, IBM DB2 on Cloud, SQL Azure, and Oracle Cloud.
