Managing Product Information Versions

摘要

Systems and methods for managing versions of product attribute information are described with respect to a number of embodiments of the present disclosure. In one implementation, a database management system that manages a database for storing attribute information of a product is described. The database management system in this implementation comprises a version control system and a querying system. The version control system is configured to enable a user to insert one or more versions of product information in the database. Each version has an effective date and is divided into a plurality of attribute groups, each attribute group containing a plurality of attributes. One or more attribute groups are modified with respect to a previous version. The version control system is further configured to record which attributes of a modified attribute group are changed. The querying system is configured to enable a user to search the database based on the effective dates of the versions.
