Temporal data refers to data, where changes over time or temporal aspects play a central role or are of interest.


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)}
di = f(ti)
[Müller and Schumann, 2003]

Time-series are a part of the broader field of time-oriented data:

Time series data is characterized by data elements being a function of time. In general, this data takes the following form:
D = {(t1, y1),( t2, y2), ..., (tn, yn)}
yi = f(ti)
[Weber et al., 2001]


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