📚 About DBMS in VTU
Database Management System (DBMS) is a core subject for Computer Science and Information Science branches under VTU. It is usually taught in the 4th semester (CBCS syllabus) and carries both theory and lab components.
DBMS is crucial as it forms the foundation for SQL, data modeling, database design, and backend development.
