What are the consequences of not defining an index on a frequently queried column?
- Database corruption issues.
- Improved query performance due to reduced overhead.
- No impact on query performance.
- Slower query performance due to full table scans.
Not defining an index on a frequently queried column can lead to slower query performance as the database engine needs to perform full table scans to locate the desired data. This results in increased overhead and longer query execution times, impacting the overall performance of the application.
