DBMS-Relational Algebra and Calculus Questions and Answers
Relational Algebra and Relational Calculus form the theoretical foundation of DBMS programming questions and answers frequently asked in technical interviews and campus placement exams such as TCS, Infosys, and Accenture. These topics explain how queries are represented and optimized in databases. By understanding operations like selection, projection, join, and division, you can effectively translate queries into SQL. Practicing DBMS MCQs and programming interview questions with answers improves your understanding of database logic, query design, and relational schema concepts essential for technical placements.
