Analytical platform for distributed data

An apparatus, comprising:

• a memory;
• and
• a processor, the processor configured to execute instructions stored in the memory to:
• generate a tree data structure comprising an exponential root node and a plurality of regular child nodes arranged in hierarchical levels, wherein a number of the hierarchical levels corresponds to a specified precision value;
• receive a numerical data value;
• truncate the numerical data value according to the specified precision value to generate a truncated value;
• store portions of the truncated value in the tree data structure, wherein to store the portions of the truncated value in the tree data structure comprises to:
• store an exponent of the truncated value in the exponential root node;
• and
• store each significant digit of the truncated value in a respective regular child node based on significance level;
• compute statistical information for each node storing a portion of the truncated value;
• and
• provide the statistical information in response to a query.

A non-transitory computer readable medium storing instructions operable to cause a processor to perform operations comprising:

• generating a tree data structure comprising an exponential root node and a plurality of regular child nodes arranged in hierarchical levels, wherein a number of the hierarchical levels corresponds to a specified precision value;
• receiving a numerical data value;
• truncating the numerical data value according to the specified precision value to generate a truncated value;
• storing portions of the truncated value in the tree data structure by:
• storing an exponent of the truncated value in the exponential root node;
• and
• storing each significant digit of the truncated value in a respective regular child node based on significance level;
• computing statistical information for each node storing a portion of the truncated value;
• and
• providing the statistical information in response to a query.
