What does the relational model promote by using independent tables?
Understand the Problem
The question is asking about the benefits of the relational model in database systems, specifically focusing on how using independent tables impacts data integrity, structural independence, data redundancy, and physical data dependence.
Answer
The relational model promotes data integrity, consistency, and reduces redundancy.
The relational model promotes data integrity, consistency, and reduces redundancy by using independent tables linked through relationships using primary and foreign keys. This model supports efficient data management and complex querying capabilities through SQL.
Answer for screen readers
The relational model promotes data integrity, consistency, and reduces redundancy by using independent tables linked through relationships using primary and foreign keys. This model supports efficient data management and complex querying capabilities through SQL.
More Information
The relational model uses normalization to minimize redundancy and dependencies by organizing data into tables with relationships. This allows organized, flexible, and scalable data storage while enabling complex data querying through SQL.
Tips
A common mistake is neglecting the importance of normalization, which helps reduce redundancy and maintain data integrity.
