database-design

Design scalable, normalized schemas with proper relationships, indexes, and migration strategies.

• Design database schemas with proper normalization
• Define relationships using primary/foreign keys
• Create strategic indexes for query performance
• Choose between SQL and NoSQL based on use case

• Normalize first, denormalize when needed
• Index strategically: query vs write trade-off
• Design for scalability from day one
• Choose right tool: SQL for relations, NoSQL for flexibility
• Migrations are forever: plan carefully
• Use composite and partial indexes wisely
• Enforce data integrity with constraints
• Plan backup and recovery in design

1. 1.Identify data modeling needs and growth patterns
2. 2.Apply normalization to reduce redundancy
3. 3.Add indexes where queries frequently filter or join
4. 4.Define relationships with proper foreign keys and cascades
5. 5.Choose SQL or NoSQL based on data access patterns
6. 6.Plan migrations with versioning and rollbacks
