Use Teradata analytic functions to analyze ordered data. Ordered data is time series data, such as clickstreams, financial transactions, and online user interactions. Teradata provides the following functions specifically for analyzing ordered data.
|nPath||Performs regular pattern matching over a sequence of rows from one or more inputs.|
|SESSIONIZE||Maps each click in a clickstream to a unique session identifier.|
To make these functions accessible, contact your Teradata Support representative.
Online help is available for each of the functions. For more detailed information, type HELP 'function_name' , for example, HELP 'SQL NPATH'.
