NeuralBlitz What I do
- Apply relational algebra and set theory
- Design normalized schemas (1NF, 2NF, 3NF, BCNF)
- Write complex SQL queries and joins
- Optimize query performance
- Implement referential integrity
When to use me
When working with relational databases, designing data models, or writing complex queries.
Key Concepts
Normalization Forms
- 1NF: Atomic values, no repeating groups
- 2NF: No partial dependencies
- 3NF: No transitive dependencies
- BCNF: Boyce-Codd normal form
- Denormalization: When and how to denormalize
Query Optimization
- Index selection and composite indexes
- Query execution plans
- Join order optimization
- Subquery vs join
- Partition pruning
Transactions
- ACID properties
- Isolation levels (READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, SERIALIZABLE)
- Locking strategies
- Deadlock prevention
- Savepoints and rollback
Advanced SQL
- Window functions
- CTEs (Common Table Expressions)
- Recursive queries
- JSON/JSONB operations
- Full-text search
- Spatial queries
Design Patterns
- Entity-Attribute-Value (EAV)
- Single Table Inheritance
- Class Table Inheritance
- Materialized paths
- Audit tables
Performance
- Query profiling
- Index maintenance
- Statistics management
- Connection pooling
- Read replicas
- Partitioning strategies
