PROLOG/ C4250 Database theory C6160 Database management systems (DBMS)Reasoning about time typically involves drawing conclusions on the basis of incomplete information. Uncertainty arises in the form of ignorance, indeterminacy, and indecision. Despite the lack of complete information, a problem ...
Because of the importance of time in Information Systems, there is a wide consensus on the need for having temporal data types and temporal queries supported as part of database standards. Actually, in the mid 90s, a forward-looking group of database researchers proposed an ambitious temporal e...
design, implementation, and application of spatio-temporal database management systems.\nThe nine coherent chapters by leading research groups are written in a tutorial style, making the research contributions of the project accessible to a wider audience interested in spatio-temporal information ...
In view of data temporality and limitations of traditional DBMS,this paper puts forward practical ways for processing temporal data in atemporal DBMS,which has reference to research achievements of contemporary scholars.It will bring helps to processing temporal data and reseach temporal database.关键词...

We also describe how the temporal mediator can provide a user interface to the multidatabase system allowing temporal queries in terms of arbitrary granularities and involving relations in different TDBMS.Page %P Close Plain text Look Inside Citations Other actions Reprints and Permissions ...
In this tutorial, you have learned how to: Create a table with a valid-time dimension Query a table with valid time support Set session-level visibility of temporal data using dbms_archive_flashback.enable_at_valid_time Resources To learn more about Oracle Database 12c refer to additional...

Efficient Temporal Coalescing Query Support in Relational Database Systems The interest in, and user demand for, temporal databases have only increased with time; unfortunately, DBMS vendors and standard groups have not moved aggr... Z Xin,F Wang,C Zaniolo - 《Lecture Notes in Computer Science》...
A temporal database contains time-varying data. In a real-time database transactions have deadlines or timing constraints. In this paper we review the substantial research in these two previously separate areas. First we characterize the time domain; then we investigate temporal and real-time data...
