Does an online MCA include DBMS?

A DBMS organises and manages structured data. MCA students should understand tables, relationships, keys, transactions, normalisation and query processing because database knowledge appears in many software roles. When preparing for an IT role, be ready to explain how DBMS works and where you would use it in a real application. This point is specifically relevant to the DBMS aspect of MCA study. For this specific question about DBMS, the practical takeaway is to relate the concept to your own MCA learning goal.
