- Focus on indexing columns that are frequently used in WHERE clauses, JOIN conditions, and ORDER BY clauses.

2. Regular Maintenance:

- Regularly rebuild and reorganize indexes to maintain their efficiency.

- Use automated scripts to perform maintenance tasks during off-peak hours.

3. Index Coverage:

- Ensure that your indexes cover all the columns required by your queries to avoid unnecessary table scans.

- Use covered indexes where possible to improve query performance.

4. Monitoring and Tuning:

- Continuously monitor query performance and index usage.

- Use tools like Query Store in SQL Server or AWR in Oracle to track query performance over time.
