“It was a very good experience for me to get such an empowering course for gaining in-depth knowledge of DBMS.”

During my online course on Database Management Systems (DBMS), I gained a thorough understanding of how data is structured, stored, and retrieved efficiently. The course covered key concepts such as database architecture, SQL queries, relational databases, and normalization. One of the highlights was learning SQL, where I practiced writing complex queries to manipulate and retrieve data, which helped me grasp the real-world application of DBMS.
