摘要
Systems and methodologies that split a table into a plurality of sub-tables, and vertical partitions. By analyzing an associated work load to determine frequently referenced columns, the subject invention supplies a compromise among various vertical partitioning strategies (e.g., candidate selection for table spilt) via a merging act, such that the table is split optimally for the work load taken as a whole Accordingly, an incoming query can optimally reference only required columns.
