Abstract: In applications like financial trading, scheduling, manufacturing and process control, time based predicates in queries and rules are very important. There is also a need to define lists of time points or intervals. We refer to these lists as calendars. This paper presents a system of calendars that allows specification of natural-language timebased expressions, maintenance of valid time in databases, specification of temporal conditions in database queries and rules, and user-defined semantics ...

Context of citations to this paper: More
.... In general, our work is based on the basic research on the time granularities and the manipulation of time granularities (e.g. see [4, 8, 9]) It is also based on the general data mining and knowledge discovery research that have appeared in the literature. More...
...of the temporal types that we have defined. Various proposals on representing granularities have appeared in the literature (e.g. [NS92, LMF86, CSS94]) The granularities expressible in these languages are all instances of our temporal types. Furthermore, software packages...
