Database Normalisation Questions
Data integrity refers to the accuracy, consistency, and reliability of data stored in a database. In the context of database normalization, data integrity ensures that the data is organized and structured in a way that eliminates redundancy and inconsistencies.
Normalization helps to achieve data integrity by breaking down a database into multiple tables and establishing relationships between them. This process eliminates data duplication and ensures that each piece of information is stored in only one place.
By adhering to normalization rules, such as the elimination of repeating groups and the establishment of primary and foreign keys, data integrity is maintained. This means that the data remains consistent and reliable, as any changes or updates made to the database will be reflected accurately throughout the system.
Overall, data integrity in database normalization ensures that the data is accurate, consistent, and reliable, which is crucial for making informed decisions and maintaining the overall quality of the database.
