An example of an AI chatbot conversation about database design interview questions.
What are some common database design interview questions I should prepare for?
Some common questions include: 1. What is normalization? 2. Explain the difference between primary and foreign keys. 3. How do you design a database for a specific application?
Can you explain normalization in more detail?
Normalization is the process of organizing data to reduce redundancy and improve data integrity. It involves dividing a database into tables and defining relationships between them.
What are the different normal forms?
The different normal forms are: 1NF (First Normal Form), 2NF (Second Normal Form), 3NF (Third Normal Form), and BCNF (Boyce-Codd Normal Form). Each form has specific rules to eliminate redundancy.
How do I decide which normal form to use?
The choice of normal form depends on the specific requirements of your application. Generally, 3NF is a good balance between normalization and performance.
