identifying one or more master data measures associated with the performance indicator from a plurality of master data measures, the performance indicator based on the one the master data measures;

for each time period of a plurality of times periods, determining a value of the one or more master data measures;

for each master data measure, determining a difference between the values of the master data measure associated with two time periods of the plurality of time period; and

preparing the determined difference for display to a user through a graphical user interface.

2 . The method of claim 1 , further comprising:

defining the plurality of master data measures based on an additional set of data; and

associating one or more of the plurality of master data measures with one or more performance indicators of a plurality of performance indicators.

3 . The method of claim 2 , further comprising, for each performance indictor of the plurality of performance indicators:

identifying a rank associated with each of the master data measures; and

ranking the plurality of master data measures that are associated with the performance indicator based on the rank associated with each of the plurality of master data measures.

4 . The method of claim 1 , further comprising:

for each time period of the plurality of times periods, determining a value of the performance indictor; and

preparing the determined value for display to the user through the graphical user interface.

5 . The method of claim 4 , wherein the value of the performance indicator is based on the value of the one or more data measures.

6 . The method of claim 1 , wherein the performance indicator is directly correlated to the one or more master data measures.

7 . The method of claim 1 , wherein the difference between the values of the one or more master data measures is greater than a threshold.

8 . The method of claim 1 , further comprising receiving, from the user, a request for analysis of the set of data, wherein identifying the performance indicator further comprises identifying the performance indicator based on the request.

9 . A computer storage medium encoded with a computer program, the program comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

identifying a performance indicator associated with a set of data, the performance indicator representing a statistical metric associated with the set of data;

identifying one or more master data measures associated with the performance indicator from a plurality of master data measures, the performance indicator based on the one the master data measures;

for each time period of a plurality of times periods, determining a value of the one or more master data measures;

for each master data measure, determining a difference between the values of the master data measure associated with two time periods of the plurality of time period; and

preparing the determined difference for display to a user through a graphical user interface.

10 . The computer storage medium of claim 9 , the operations further comprising:

defining the plurality of master data measures based on an additional set of data; and

associating one or more of the plurality of master data measures with one or more performance indicators of a plurality of performance indicators.

11 . The computer storage medium of claim 10 , the operations further comprising, for each performance indictor of the plurality of performance indicators:

identifying a rank associated with each of the master data measures; and

ranking the plurality of master data measures that are associated with the performance indicator based on the rank associated with each of the plurality of master data measures.

12 . The computer storage medium of claim 9 , the operations further comprising:

for each time period of the plurality of times periods, determining a value of the performance indictor; and

preparing the determined value for display to the user through the graphical user interface.

13 . The computer storage medium of claim 12 , wherein the value of the performance indicator is based on the value of the one or more data measures.

14 . The computer storage medium of claim 9 , wherein the difference between the values of the one or more master data measures is greater than a threshold.

15 . A system of one or more computers configured to perform operations comprising:

identifying a performance indicator associated with a set of data, the performance indicator representing a statistical metric associated with the set of data;

identifying one or more master data measures associated with the performance indicator from a plurality of master data measures, the performance indicator based on the one the master data measures;

for each time period of a plurality of times periods, determining a value of the one or more master data measures;

for each master data measure, determining a difference between the values of the master data measure associated with two time periods of the plurality of time period; and

preparing the determined difference for display to a user through a graphical user interface.

16 . The system of claim 15 , the operations further comprising:

defining the plurality of master data measures based on an additional set of data; and

associating one or more of the plurality of master data measures with one or more performance indicators of a plurality of performance indicators.

17 . The system of claim 16 , the operations further comprising, for each performance indictor of the plurality of performance indicators:

identifying a rank associated with each of the master data measures; and

ranking the plurality of master data measures that are associated with the performance indicator based on the rank associated with each of the plurality of master data measures.

18 . The system of claim 15 , the operations further comprising:

for each time period of the plurality of times periods, determining a value of the performance indictor; and

preparing the determined value for display to the user through the graphical user interface.

19 . The system of claim 18 , wherein the value of the performance indicator is based on the value of the one or more data measures.

20 . The system of claim 15 , wherein the difference between the values of the one or more master data measures is greater than a threshold.
