AN IMPLEMANTATION OF BITEMPORAL TEMPORAL RELATIONAL DATABASE MANAGEMENT SYSTEMS
Abstract :
This paper presents an implementation of a nested bitemporal relational data model that allows more than one level of nesting. The fundamental construct for representing temporal data is a Bitemporal Atom (BTA) that consists of five parts: valid time period, the time periods’ lower and upper bounds this data is recorded in the database and a value. Bitemporal data is attached to attributes and applied as an abstract data type. A number of examples of the management of nested bitemporal data model and queries to demonstrate the features of the model are provided. A prototype implementation has been completed in an object-relational database system to demonstrate the feasibility of the model.
