FAQs on How to Design DB Tables for any Application? (The Basics) Video Lecture - Database Management System (DBMS) - Computer Science Engineering (CSE)
| 1. How can I determine the relationships between different tables in a database design? |  |
Ans. To determine the relationships between different tables in a database design, you should analyze the data and identify how entities are related to each other. Common types of relationships include one-to-one, one-to-many, and many-to-many.
| 2. What are the primary keys and foreign keys in database tables? | |
Ans. Primary keys are unique identifiers for each record in a table, while foreign keys are used to establish relationships between tables by referencing the primary key of another table.
| 3. How do I ensure data integrity in my database tables? | |
Ans. You can ensure data integrity in your database tables by setting constraints such as unique constraints, foreign key constraints, and not null constraints. These constraints help maintain the accuracy and consistency of data.
| 4. What is normalization in database design and why is it important? | |
Ans. Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It is important because it helps eliminate data anomalies and ensures efficient storage and retrieval of data.
| 5. How can I optimize database tables for better performance? | |
Ans. You can optimize database tables for better performance by indexing frequently searched columns, minimizing the use of NULL values, and avoiding unnecessary joins in queries. Additionally, you can consider denormalizing tables in certain cases to improve query performance.
