Contains a row of summary information for each type of SQL operation. Each row summarizes all SQL activity for that type of SQL operation. This information provides the user with a high level indication of the type of SQL statements used. For example, are the applications mainly read-only, or is there a large amount of update, delete, or insert activity. This information can then be used to try specific performance tuning techniques. For example, if a large amount of INSERT activity is occurring, perhaps using an OVRDBF command to increase the blocking factor or perhaps use of the QDBENCWT API is appropriate.
