Method and system for long-term update and edit control in a database system

摘要

Aspects for allowing long term, update and edit control in a database system are described. The aspects include providing library control functions in a database system, and utilizing the library control functions via structured query language statements to ensure data integrity of opaque data types in the database system. Provision of the library control functions further includes providing a checkout function and creating a set of update and delete triggers in correspondence with the checkout function.
