Temporal data refers to a series of data originating in one concept (stochastic variable) yet varying over time and ordered accordingly.

Definitions

Temporal data is data that varies over time.
[Jensen and Snodgrass, 1999]


A temporal data denotes the evolution of an object characteristic over a period of time.
[Daassi and Nigay, 2004]


Time dependent data is characterized by data elements being a function of time. In general, data takes the form
d = f(t)

For data defined at discrete time stamps ti, this relation can be represented as:

D = {(t1, d1),( t2, d2), ..., (tn, dn)}
where
di = f(ti)
[Müller and Schumann, 2003]


Remarks

Applying exploratory (esp. timelines) as well as confirmatory methods, temporal data can be used to analyze the influence of time on a certain variable.

Synonyms

  • temporal data
  • time-oriented data
