Data Retrieval (Fetching Data)
The most critical role of SQL is retrieving specific data quickly using commands like:
SELECT
WHERE
JOIN
ORDER BY
Organizations rely on SQL queries to generate reports, analyse trends, and support key business decisions. For example, an e-commerce company retrieves purchase history, customer details, and order statistics using SQL queries.
Data Manipulation
SQL allows users to:
Insert new records
UPDATE already existing data
Delete extra data (DELETE)
This makes data management flexible and efficient. In business operations, data manipulation ensures accuracy and up-to-date information.
Creation and Administration of Database
SQL helps create and modify database structures by using:
CREATE
ALTER
DROP
Administrators build tables, relationships, indexes, and constraints entirely through SQL commands.
Security of Data
SQL provides high-level security through:
User permissions
Role-based access
Data limitations
Companies protect sensitive information—like financial data, customer records, and sales performance—through SQL security commands.
Data Integrity and Consistency
SQL defines rules such as:
Primary keys
Foreign keys
Unique constraints
Check constraints
These ensure that data remain consistent, accurate, and relia
Performance Optimisation
SQL supports indexing, query optimization, and execution planning. This helps improve application performance and ensures faster data operations.

SQL plays a vital role in supply chain operations because supply chain systems heavily rely on large-scale databases.
