Algorithm for determining piece-wise homogeneity of data

A system for handling information in which data is aggregated about work requests associated with a service class period and a report class, said information handling system comprising at least a processor carrying out machine instructions causing said system to:

• record metadata along with each report class period, said metadata comprising a service class name and a signature;
• update said service class name and change said signature each time a unit of work is aggregated into the report class and said service class name associated with said unit of work is different from a service class name previously recorded;
• compare samples of total values taken at a beginning and end of an interval;
• and
• determine the aggregated data to be homogeneous when a signature sampled at said beginning of said interval is the same as a signature sampled at said end of said interval and determine the aggregated data to be heterogeneous when said signature sampled at said beginning of said interval is different from said signature sampled at said end of said interval.

A storage medium encoded with machine-readable computer program code for managing an information handling system in which data is aggregated about work requests associated with a service class period and a report class, said storage medium including instructions for causing said system to implement a method comprising:

• recording metadata along with each report class period, said metadata comprising a service class name and a signature;
• updating said service class name and changing said signature each time a unit of work is aggregated into the report class and said service class name associated with said unit of work is different from the service class name previously recorded;
• comparing samples of total values taken at a beginning and end of an interval;
• determining the aggregated data to be homogeneous when a signature sampled at said beginning of said interval is the same as a signature sampled at said end of said interval and determining the aggregated data to be heterogeneous when said signature sampled at said beginning of said interval is different from said signature sampled at said end of said interval.
