Question

What are the basic operations of a rational Database management system?

Answer 1

The basic operations of a rational Database Management System (DBMS) include insert, retrieve, update, delete, and join.

Step-by-step explanation:

A rational Database Management System (DBMS) performs several basic operations to manage and manipulate data. These operations include:

1. Insert: Adding new records or data into the database.
2. Retrieve: Fetching data from the database based on specified criteria.
3. Update: Modifying existing data in the database.
4. Delete: Removing records or data from the database.
5. Join: Combining data from multiple database tables using common fields.

For example, if you have a rational DBMS storing customer information, you can use the insert operation to add a new customer, the retrieve operation to find all customers who have made a purchase in the last month, the update operation to change a customer's address, and the delete operation to remove a customer who has canceled their account.
