ENCODED VERSION COLUMNS OPTIMIZED FOR CURRENT VERSION ACCESS

摘要

Embodiments of the present invention provide techniques for optimizing access to different versions of records within a database. Embodiments of the invention optimize the access to different versions of records by using an encoded version column (EVC) within database tables. Furthermore, embodiments of the invention provide a method for assigning EVC values for data records which have an EVC. Access to versions of records within a database table containing an EVC may be optimized based on the EVC value.
