Core Principles of Database Design

When designing a database, it's essential to follow these principles:

  • Normalization: Reduce redundancy by organizing data into related tables.
  • Scalability: Structure schemas to handle growth efficiently.
  • Consistency: Enforce rules to maintain uniform data formatting.
  • Security: Implement access controls and encryption where necessary.

Database Normalization

Normalization is a process to organize data in a database.

  1. First Normal Form (1NF): Ensure atomic values in each column.
  2. Second Normal Form (2NF): Remove partial dependencies.
  3. Third Normal Form (3NF): Eliminate transitive dependencies.

Index Optimization

Indexes improve query performance but should be used wisely:

  • Create indexes on frequently queried columns.
  • Avoid over-indexing to prevent write overhead.
  • Use composite indexes for multi-column queries.

Security Best Practices

  • Use role-based access control (RBAC) to limit permissions.
  • Regularly audit database activities.
  • Encrypt sensitive data both at rest and in transit.
