Designing Access Methods for Bitemporal Databases
By supporting the valid and transaction time dimensions, bitemporal databases represent reality more accurately than conventional databases. In this paper, we examine the issues involved in designing efficient access methods for bitemporal databases, and propose the partial-persistence and the double-tree methodologies. The partial-persistence methodology reduces bitemporal queries to partial p...
متن کاملTPC-BiH: A Benchmark for Bitemporal Databases
An increasing number of applications such as risk evaluation in banking or inventory management require support for temporal data. After more than a decade of standstill, the recent adoption of some bitemporal features in SQL:2011 has reinvigorated the support among commercial database vendors, who incorporate an increasing number of relevant bitemporal features. Naturally, assessing the perfor...
متن کاملAn Incremental Index for Bitemporal Databases
Bitemporal databases record not only the history of tuples in temporal tables, but also record the history of the databases themselves. Indexing structures, which are a critical issue in traditional databases, became even more critical for bitemporal databases. We address this problem by investigating an incremental indexing structure based on R-trees, called the HR-tree, which was originally a...
متن کاملLogical Data Partitioning in Bitemporal Databases
A bitemporal database is a database explicitly supporting two temporal coordinates, namely the valid time and the transaction time. In this paper we introduce the concept of logical data partitioning in bitemporal databases, where data are partitioned into blocks according to their own natural (temporal) properties and independently on the particular application. In this framework we consider b...
متن کاملOn Effective Data Clustering in Bitemporal Databases
Temporal databases provide built-in supports for efficient recording and querying of time-evolving data. In this paper, data clustering issues in temporal database environment are addressed. Data clustering is one of the most effective techniques that can improve performance of a database system. However, data clustering methods for conventional databases do not perform well in temporal databas...
