In the context of normalization, what is a primary key?

Detailed Solution for Test: Database - Question 1

Which of the following statements best describes the concept of normalization in a relational database?

Detailed Solution for Test: Database - Question 2
Normalization is a systematic approach to organizing and structuring a relational database to eliminate data redundancy and anomalies such as insertion, update, and deletion anomalies. It involves breaking down tables into smaller, related tables to ensure data integrity and consistency. By doing so, we can avoid the issues that arise when data is duplicated across tables, leading to inconsistencies and inefficiencies in data management.

Which normal form deals with eliminating transitive dependencies between non-key attributes?
Detailed Solution for Test: Database - Question 9
Boyce-Codd Normal Form (BCNF) deals with eliminating transitive dependencies between non-key attributes by ensuring that every determinant (a column that determines the values of other columns) is a candidate key. This helps to further reduce data redundancy and anomalies.
