An Implementation of Bitemporal Relational Database Management Systems

An Implementation of Bitemporal 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.

Bu makale birden fazla seviyede içiçe geçmişliği mümkün kılan çift zamanlı ilişkisel veri modelinin uygulanma araştırmasını içerir. Zamansal veriyi betimlemenin temel yapısı olan Çift Zamanlı Atom beş bölümden oluşur; olay zamanı periyodu, bu verinin veri tabanına işlenme zaman dönemlerinin alt ve üst sınırları ve yeni veri değeri. Çift zamanlı veri özniteliklerde bulunmaktadır ve soyut veri tipi olarak uygulanmıştır. İçiçe geçmiş çift zamanlı veri modeli yönetimi için örnekler, modelin özelliklerini göstermek için sorgulamalar sunulmuştur. Örnek uygulama modelin yapılabilirliğini göstermek için nesnesel-ilişkisel veri tabanı sisteminde tamamlanmıştır.
