SQL Profiler:
- SQL Profiler is a tool for monitoring and analyzing SQL Server database activities.
- It helps track query performance, identify bottlenecks, and troubleshoot issues.
Query Optimization:
- Query optimization involves improving the performance of SQL queries by optimizing their execution plans.
- Techniques include indexing, rewriting queries, and using appropriate joins.
Performance Tuning:
- Performance tuning involves making adjustments to a database system to enhance its speed and efficiency.
