What are the characteristics of good database design?

Good database design is essential for creating a system that effectively manages data and meets the needs of its users. The characteristics identified in the correct answer include simplicity, scalability, flexibility, and data integrity.

Simplicity ensures that the database is easy to understand and use, which is crucial for both developers and end-users. A simple design minimizes confusion and makes it easier to maintain, update, and query the database. This leads to a lower likelihood of errors and enhances the efficiency of operations.

Scalability refers to the database's ability to grow and accommodate increasing amounts of data and users without significant performance degradation. A scalable database can adapt to changing requirements over time, which is important as organizations evolve and their data needs expand.

Flexibility allows a database to adapt to new requirements or changes in the data model without extensive rework. A flexible design can incorporate new data types or structures, making it easier to keep the database relevant as business needs change.

Data integrity is critical for maintaining the accuracy and consistency of the data within the database. This characteristic ensures that the data adheres to certain rules and constraints, which helps to prevent errors and ensures that users can rely on the information provided by the database.

Overall, these characteristics contribute to a well-structured and
