Time series data is sequence of well defined numerical data points in successive order, usually occurring in uniform intervals. In other words a time series is simply a sequence of numbers collected at regular intervals over a period of time. For example the daily prices of a particular stock can be considered as time series dada. Data mining, also popularly known as Knowledge Discovery in Databases (KDD), refers to the nontrivial extraction of implicit, previously unknown and potentially useful information from data in databases. Time series databases introduce new aspects and difficulties to data mining and knowledge discovery due to their high dimensionality nature.
