Statistic normalization in a data store system

A computer-implemented method comprising:

• generating a plurality of statistical values on a data store table from a plurality of data store tables stored in an array of persistent storage devices, wherein each statistical value is associated with a statistical category, and wherein each statistical category defines a respective characteristic about the overall content of one or more columns of a data store table;
• retrieving a set of rules associated with the statistical categories, wherein each rule comprises a relationship between values of at least two statistical categories;
• evaluating the set of rules based on the plurality of statistical values;
• in response to the determination that at least one rule of the set of rules is violated, adjusting a value of at least one of the plurality of statistical values;
• storing the plurality of statistical values in at least one of the persistent storage devices;
• receiving a query on the data store table;
• and
• using at least of one the stored plurality of statistical values to generate a response to the query.

A non-transitory computer-readable medium encoded with a plurality of instructions executable by a process, the plurality of instructions comprising:

• instructions to generate a plurality of statistical values on a data store table from a plurality of data store tables stored in an array of persistent storage devices, wherein each statistical value is associated with a statistical category, and wherein each statistical category defines a respective characteristic about the overall content of a column one or more columns of a data store table;
• instructions to retrieve a set of rules associated with the statistical categories, wherein each rule comprises a relationship between values of at least two statistical categories;
• instructions to evaluate the set of rules based on the plurality of statistical values;
• in response to the determination that at least one rule of the set of rules is violated, instructions to adjust a value of at least one of the statistical values;
• instructions to store of the plurality of statistical values in at least one of the persistent storage devices;
• instructions to receive a query on the data store table;
• and
• instructions to use at least one of the stored plurality of statistical values to generate a response to the query.
