A Study of Temporal Database Research

Shailender Kumar

Abstract


A wide range of database applications manage time-varying data. These applications are termed as temporal databases or time-oriented database applications that are considered as repositories of time-dependent data. The research in the area of temporal databases has made significant contributions in characterizing the semantics of such information and in providing expressive and efficient means to manage temporal data. This paper shortly summarizes the work done by researchers in the area of temporal data management, surveys towards solutions to challenging aspects of temporal data management, and list several unanswered research questions.

Keywords
