Working with Temporal Data

Abstract

It’s probably fair to say that time is a critical piece of information in almost every useful database. Imagining a database that lacks a time component is tantamount to imagining life without time passing; it simply doesn’t make sense. Without a time axis, it is impossible to describe the number of purchases made last month, the average overnight temperature of the warehouse, or the maximum duration that callers were required to hold the line when calling in for technical support.
