Solution Management for Current Temporal Aspect Using Tuple Versions

摘要

The current temporal paradigm is based on the validity, which delimits each data tuple by the time frame. The uni-temporal solution extends the object identifier with the validity interval inside the primary key. It can be used on various granularities (object, attribute, and group), however, it cannot store individual versions for existing data corrections. This paper references temporal architectures highlights current challenges for dealing with data versions and proposes own solution replacing transaction time frame forming transaction reliability concept. It deals with the referential integrity in the temporal environment and proposes a model for covering references and ensuring the integrity of the processed data using signature hash values, two-level indexes formed by the object and individual states with corrections.
