the value of the index's update count (user_updates) is large, the maintenance volume is large. For more information, see the number of searches (user_seeks) and the number of bookmarked search operations (user_lookups ), if the two values are small, you can consider deleting the index. When you restart the SQL SERVER service, various counters in the sys. dm_db_

improve query efficiency, we must also pay attention to its cost Indexes require space for storage and regular maintenance, and the index itself is modified whenever a record is added or subtracted from the table or the index column is modified This means that the insert, DELETE, and update for each record will pay 4 or 5 more disk I/O Because indexes require additional storage space and processing, unnecessary indexing slows query response times

SQL Server is a relational database management system that was originally developed by the Microsoft,sybase and ashton-tate three companies and launched the first OS/2 version in 1988.
