Method and Apparatus for Access, Integration, and Analysis of Heterogeneous Data Sources Via the Manipulation of Metadata Objects |
摘要 |
A computer-based method represents a subset of a dataset table of rows and columns. The method includes selecting a set of blocking variables corresponding to blocking columns of the dataset table. For each row in the dataset table, a tuple of values for the blocking columns uniquely identifies the row within the dataset table. The method also includes selecting a set of non-blocking variables that correspond to columns of the subset. The set of non-blocking variables does not intersect the set of blocking variables. The method also includes creating a block information structure that includes both the set of non-blocking variables and, for each blocking variable in the set of blocking variables, a set of values.
