what is sql optimization
Answer / anupam bhatt
SQL optimization or tuning is the process to improve upon your sql queries to make them more efficient and avoid common pitfalls like multiple database round trips etc. Basically do more work with fewer queries to make the application fast and manageable.
This can be achieved by various ways like joining multiple queries in to one to avoid multiple network round trips, add indexes to the tables which are frequently accessed to reduce the turnaround time, fetch only the required data instead of a generic query getting all of the data of the table etc.
