Abstract:
1. A machine-accessible storage medium having computer-executable instructions that, upon execution by a processor, cause the processor to perform a method of database performance data processing comprising: setting a value of a time window size TP, where TP is a time period between a current moment of time t and a moment of time TP periods ago, t−TP+1; obtaining a value of a database performance statistic of at least one database in the current moment of time t as VAL(t); determining a highest value of the database performance statistic of the at least one database within a time period from t−TP+1 to t, as HV(t); determining a lowest value of the database performance statistic of the at least one database within the time period from t−TP+1 to t, as LV(t); and calculating a normalized value of a data point at time t of the at least one database as (VAL(t)−LV(t))/(HV(t)−LV(t)); determining the performance of the at least one database based on the calculated normalized value.
