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.
