METHOD AND APPARATUS FOR ACCESS, INTEGRATION AND ANALYSIS OF HETEROGENEOUS DATA SOURCES VIA THE MANIPULATION OF METADATA OBJECTS

摘要

A kind of computer based method, indicates the row and column of the table of the subset of data set. This method includes the table that selection corresponds to one group of block variable house pillar collection. For every a line in data set table, the value house pillar unquely of tuple identifies the table of the row in the data set. This method further includes the subset of the corresponding column of the clog-free variable point of one group of selection. Various clog-free variables do not interfere various block variables to intersect. This method further includes one block message structure (30) of creation including organizing the clog-free variable (30b) of the two, and for each block variable set block variable (30a), a class value.
