“The Online Course on Database Management Systems (DBMS)”
One of the key strengths of the course is its accessibility for both beginners and those with some prior experience. The pace of the lessons is balanced, and the concepts are explained with clarity. However, adding more advanced topics, such as NoSQL databases and database optimization techniques, would make it more comprehensive. Additionally, live sessions or interactive doubt-clearing forums could further enrich the learning experience.

“Uniqueness: A Primary Key Uniquely Identifies”
A primary key uniquely identifies each record in a table. No two rows can have the same primary key value. A primary key column cannot contain NULL values. Every row must have a value for the primary key. A primary key can consist of a single column or multiple columns (composite key). Primary keys are automatically indexed, which helps in faster retrieval of records. The primary key constraint enforces entity integrity by ensuring that each record is unique.
