Time series data is stored in a specialized table that contains a structure called a primary time index (PTI). PTI tables are created using the time series forms of CREATE TABLE or CREATE TABLE AS, which have a PRIMARY TIME INDEX clause. PTI tables also contain system-generated columns of time information. Teradata Database uses the time information to organize the data across the system.

For guidelines on choosing the primary time index (PTI) to result in an even distribution of your type of data, see Guidelines for Choosing a Primary Time Index.
