Database Design Best Practices for Scalable Applications

Design databases that scale with your application while maintaining performance.

Good database design prevents performance problems and supports application growth. Foundation decisions are hard to change later.

Design Principles

Normalization Reduce redundancy and improve data integrity through proper normalization.

Indexing Strategy Index columns used in queries, but don't over-index.

Data Types Choose appropriate data types for storage efficiency and query performance.

Relationships Model relationships correctly with proper foreign keys.

Scalability Considerations

- Plan for data growth from the start - Consider read vs write patterns - Evaluate partitioning strategies - Plan for backup and recovery - Document your schema thoroughly
