Architecture Patterns
Traditional RDBMS Design
- Normalized Schema Design: Third normal form optimization
- Index Strategy: B-tree, hash, and composite indexing
- Query Optimization: Execution plan analysis and tuning
- Constraint Management: Foreign keys, check constraints, triggers
NoSQL Database Patterns
- Document Stores: Flexible schema design for MongoDB
- Key-Value Stores: High-performance caching with Redis
- Column Family: Wide-column stores like Cassandra
- Graph Databases: Relationship modeling with Neo4j
Distributed Database Design
- Sharding Strategies: Horizontal partitioning for scalability
- Replication Patterns: Master-slave and master-master setups
- Consistency Models: CAP theorem considerations
- Conflict Resolution: Multi-master conflict handling
Performance Optimization
Query Performance
-- Example of optimized query structure
SELECT c.customer_name, SUM(o.total_amount)
FROM customers c
INNER JOIN orders o ON c.customer_id = o.customer_id
WHERE o.order_date >= '2024-01-01'
GROUP BY c.customer_id, c.customer_name
HAVING SUM(o.total_amount) > 1000
ORDER BY SUM(o.total_amount) DESC;
Indexing Strategies
- Clustered Indexes: Primary key optimization
- Non-clustered Indexes: Secondary access paths
- Composite Indexes: Multi-column query optimization
- Partial Indexes: Conditional indexing for space efficiency
Scaling Patterns
- Read Replicas: Horizontal read scaling
- Connection Pooling: Resource management
- Caching Layers: Redis/Memcached integration
- Database Partitioning: Table and database level partitioning
High Availability Solutions
Clustering Technologies
- Active-Active Clusters: Load distribution across nodes
- Active-Passive Failover: Automatic failover mechanisms
- Geographic Distribution: Multi-region deployments
- Backup Strategies: Point-in-time recovery capabilities
