3. Principles and Techniques of Database Design

Principles of database design

 
  • Data Integrity: Ensuring data is accurate, consistent, and reliable by preventing duplicates and establishing relationships between tables.
  • Normalization: Organizing data into tables to reduce redundancy and minimize data anomalies that can occur during insertions, updates, or deletions.
  • Scalability: Designing the database to handle future growth in data volume and user numbers without compromising performance or integrity.
  • Performance: Structuring the database for fast query and data retrieval. This is achieved through techniques like proper indexing and efficient data modeling.
  • Security: Implementing measures to protect sensitive data from unauthorized access and breaches.
  • Flexibility and Maintainability: Creating a design that is easy to update, modify, and extend in the future. This includes using consistent naming conventions and good documentation
