A system for profile record generation of input records, the system comprising: a record processor which converts the input records into a data records suitable for the profile record generation; and a statistics engine for the generation of profile records based on the data records. Furthermore, system optimization can be obtained by use of a task control method that sub-divides the aggregations of profile records into units of work that can be individually performed, the method comprising: partitioning based on a pre-determined partitioning key associated with entities to be profiled, wherein the association between the partitioning key and the entities being profiled is varied in order to optimize the profiling performance. |
