Abstract:
Data segment-based indexing includes identifying data segments of a column of a database based on a data distribution of data of the column, indexing the data segments, including, for each data segment, determining an index type and creating an index of the determined index type, and building a composite link between indexes of a common index type, which indexes of the common index type include a created index, from indexing the data segments of the column, of the common index type and at least one other index, of the common index type, which is for other data segment(s), of other column(s) of the database, that have been indexed using the common index type. The composite link provides for parallel searching against the indexes in the group to search corresponding different data segments, in different columns of the database, indexed using the common index type.
