A time series database (TSDB) is a software system that is optimized for storing and serving time series through associated pairs of time(s) and value(s). Both models and applications can be developed under each of these conditions, although the models in the latter case might be considered as only partly specified. If determining a unique record requires a time data field and an additional identifier which is unrelated to time (e.
In addition, time-series analysis can be applied where the series are seasonally stationary or non-stationary.
A time series is very frequently plotted via a run chart (which is a temporal line chart). Further references on nonlinear time series analysis: (Kantz and Schreiber),32 and (Abarbanel)33
