MSBTE 313302 Database Management System Lab
Manual Answers K Scheme 3rd Semester is an important part of the diploma
engineering curriculum. It focuses on designing, managing, and handling
databases efficiently using SQL and relational database concepts. The lab
manual guides students through practical database creation, query execution,
normalization, transactions, triggers, and PL/SQL programming.
Understanding DBMS is essential
because databases are the backbone of every IT application, from banking
systems to e-commerce platforms. With this lab manual, students gain hands-on
experience with SQL queries, ER models, relational algebra, and advanced
database techniques.

Answers:
Q1. What is a database?
Answer: A database is an organized collection of structured data stored
electronically for easy access and management.
Q2. Define DBMS.
Answer: DBMS (Database Management System) is software used to create, manage,
and manipulate databases.
Q3. What is RDBMS?
Answer: RDBMS (Relational DBMS) organizes data into tables with rows and columns
and uses SQL for queries.
Q4. What is SQL?
Answer: SQL (Structured Query Language) is used to communicate with relational
databases.
Q5. What are the types of SQL commands?
Answer: DDL, DML, DCL, and TCL.
Q6. What is DDL?
Answer: Data Definition Language – used to define database schema (e.g., CREATE,
ALTER, DROP).
Q7. What is DML?
Answer: Data Manipulation Language – used for data modification (e.g., INSERT,
UPDATE, DELETE).
Q8. What is DCL?
Answer: Data Control Language – controls user access (e.g., GRANT, REVOKE).
Q9. What is TCL?
Answer: Transaction Control Language – manages transactions (e.g., COMMIT,
ROLLBACK, SAVEPOINT).
Q10. What is a primary key?
Answer: A primary key uniquely identifies each record in a table.
Q11. What is a foreign key?
Answer: A foreign key establishes a relationship between two tables.
Q12. What is normalization?
Answer: Normalization is the process of organizing data to reduce redundancy and
improve consistency.
Q13. What is 1NF?
Answer: First Normal Form ensures atomic values and no repeating groups.
Q14. What is 2NF?
Answer: Second Normal Form removes partial dependency on composite primary keys.
Q15. What is 3NF?
Answer: Third Normal Form removes transitive dependencies.
Q16. What is a join in SQL?
Answer: A join is used to combine rows from two or more tables based on related
columns.
Q17. Types of joins?
Answer: Inner join, left join, right join, full join, self join, cross join.
Q18. What is a view?
Answer: A view is a virtual table based on the result of an SQL query.
Q19. What is an index?
Answer: An index improves the speed of data retrieval in a table.
Q20. What is a transaction?
Answer: A transaction is a unit of work in a database that must be executed
fully or not at all.
Q21. Define ACID properties.
Answer: Atomicity, Consistency, Isolation, Durability – ensure reliable
transactions.
Q22. What is concurrency control?
Answer: It manages simultaneous database operations without conflicts.
Q23. What is a trigger?
Answer: A trigger is a stored program executed automatically in response to
specific database events.
Q24. What is a cursor?
Answer: A cursor is a pointer that allows row-by-row processing of query results
in PL/SQL.
Q25. What is PL/SQL?
Answer: PL/SQL (Procedural Language SQL) is an extension of SQL that supports
procedural programming.
Q26. What is a stored procedure?
Answer: A stored procedure is a precompiled set of SQL statements stored in the
database.
Q27. Difference between delete and truncate?
Answer: DELETE removes selected rows, TRUNCATE removes all rows and resets
memory.
Q28. What is a composite key?
Answer: A composite key consists of two or more columns used together as a
primary key.
Q29. What is data integrity?
Answer: Data integrity ensures accuracy and consistency of data in a database.
Q30. Why is DBMS important for computer engineers?
Answer: It provides essential skills for designing, managing, and developing
real-world applications involving data.
