Importance of Database Design

Effective database design is essential for several reasons:

  • Efficiency: Properly designed databases ensure that data is stored efficiently and can be retrieved quickly, enhancing the overall performance of the system.
  • Scalability: A good design makes it easier to scale the database as the amount of data grows or as the application requirements change.
  • Data Integrity: Ensures that the data remains accurate and consistent throughout its lifecycle.
  • Maintenance: Simplifies maintenance tasks, such as updates and backups, reducing the risk of errors and downtime.
