Database Query Processing Using Horizontal Data Record Alignment of Multi-Column Range Summaries

摘要

Organizing data within a database is provided. In response to determining that a group of coarsified data records within a database table is not an aligned group of data records, a virtually replicated subgroup of coarsified data records that corresponds to the group of coarsified data records is generated from different groups of coarsified data records within the database table. The virtually replicated subgroup of coarsified data records is aligned with the corresponding group of coarsified data records.
