Top 10 Questions for Computer Applications Engineer Interview

1. What is the difference between a DBMS and a database?

• A DBMS is a software system that allows users to create, manage, and access databases.
• A database is a collection of related data that is organized and stored in a computer system.

2. What are the different types of DBMSs?

Relational DBMS

• Stores data in tables with rows and columns.
• Uses SQL to access and manipulate data.

Object-Oriented DBMS

• Stores data as objects with properties and methods.
• Uses object-oriented programming languages to access and manipulate data.

3. What is the difference between a primary key and a foreign key?

• A primary key is a unique identifier for each row in a table.
• A foreign key is a column in a table that references a primary key in another table.

4. What is the purpose of normalization?

• Normalization is a process of organizing data in a database to reduce redundancy and improve data integrity.
• There are three main normal forms: first normal form (1NF), second normal form (2NF), and third normal form (3NF).

5. What is the difference between a stored procedure and a trigger?

• A stored procedure is a set of SQL statements that are stored in the database and can be executed as a unit.
• A trigger is a database object that is executed automatically when a specific event occurs, such as the insertion, deletion, or update of data in a table.

6. What are the different types of database indexes?

• Clustered index: A clustered index physically orders the data in the table based on the index key.
• Non-clustered index: A non-clustered index creates a separate structure that maps the index key to the row’s physical location in the table.

7. What are the advantages and disadvantages of using a database management system?

Advantages

• Centralized data storage and management.
• Improved data integrity and security.
• Increased efficiency and productivity.

Disadvantages

• Cost of implementation and maintenance.
• Complexity of administration.
• Performance issues with large databases.

8. What are the key considerations for choosing a database management system?

• Type of data to be stored.
• Volume of data.
• Concurrency requirements.
• Security requirements.

9. What are the best practices for database design?

• Normalize the data.
• Use appropriate data types.
• Create meaningful indexes.
• Optimize queries.

10. What are the emerging trends in database technology?

• Cloud databases.
• NoSQL databases.
• Big data analytics.
• Machine learning and AI in databases.
