Updating database statistics
Accurate and up-to-date statistics are important to the efficient performance of SQL Server. We recommend that the database administrator update statistics for the PowerSchool SMS system’s database at least once a month. When updating statistics, it is also useful to recompile the stored procedures. The database administrator can use a script in Query Analyzer for these tasks.
