What is the primary advantage of a relational database?

The primary advantage of a relational database lies in its ability to reduce data redundancy. This is achieved through the use of normalization, which organizes data into tables and ensures that data is only stored once, eliminating unnecessary duplication. By establishing relationships between different tables, relational databases efficiently manage data in a manner that maintains integrity and consistency.

This streamlined organization allows for easier updates and modifications, preventing discrepancies that can occur when the same data exists in multiple locations. Moreover, the structured format of relational databases facilitates querying and reporting, enabling users to extract required information without wading through redundant data.

In contrast, while enhanced security, improved data speed, and ease of use for non-technical users are all potential benefits of relational databases or database management systems, they are not the core advantage that defines the relational model. The focus on minimizing data redundancy distinguishes relational databases as a robust solution in managing data efficiently and effectively.
