Use referential integrity constraints (e.g., foreign key constraints) to maintain data consistency and enforce data integrity rules across related tables. Designing an ER Diagram for a Hospital Management System.
- Indexing: Identify frequently queried columns and create appropriate indexes to improve query performance. Balance the benefits of indexing with the overhead of index maintenance, and avoid over-indexing which can degrade performance during data modification operations.
- Partitioning: Consider partitioning large tables to improve manageability and performance. Partition tables based on frequently accessed data ranges (e.g., by date or patient ID), which can enhance query performance and simplify data archiving and deletion processes.
- Optimize Queries: Write efficient SQL queries by avoiding unnecessary joins, using appropriate WHERE clauses, and optimizing aggregation and sorting operations. Utilize database query execution plans and profiling tools to identify and resolve performance bottlenecks.
- Denormalization: Evaluate the trade-offs of denormalizing certain data structures to optimize query performance in read-heavy scenarios. Denormalization can involve duplicating data across tables to reduce join operations and improve query execution times, but it may increase storage requirements and complicate data maintenance.
