Time Dimension Formulas

Time Dimension Formulas

Use formulas to populate the next logical dimension slice for a time dimension. The value of the dimension slice begins where the value of the previous dimension slice ended.
The initial segmentation process creates a segment for each dimension slice in the data classification, plus a default segment for new transactions and transactions that do not meet the business rule criteria of other segments. Over time, the default segment becomes larger and database performance degrades. To avoid performance degradation you must periodically create a new default segment, split the current default segment, or create a new non-default segment to move data to. Before you redefine the default segment or create a new one, you must create a dimension slice that specifies the values of the new or redefined segment.
If you plan to use the time dimension to create segments by year or quarter, you can use a formula to simplify the process of redefining or creating a new default segment. Before you run a segmentation policy for the first time, select a formula in the data classification that you plan to apply to the segmentation group. The formula creates and determines the value of the next logical dimension slice that Data Archive uses to redefine the default segment or create a new one.
Formulas use a specific naming convention. If you use a formula in a data classification, you must name the dimension slices you create according to the formula naming convention.
The following table describes the formula naming conventions:
Naming Convention
Formula Description
YYYY
Creates a dimension slice with a value of one year, such as January 01, 2013-December 31, 2013. If you use the YYYY formula, you must name the dimension slices for the dimension in the YYYY format, such as "2013."
QQYY
Creates a dimension slice with a value of one quarter, such as January 01, 2013-March 31, 2013. If you use the QQYY formula, you must name the dimension slices for the dimension in the QQYY format, such as "0113" for the first quarter of 2013.
YYYYQQ
Creates a dimension slice with a value of one quarter, such as January 01, 2013-March 31, 2013. If you use the YYYYQQ formula, you must name the dimension slices for the dimension in the YYYYQQ format, such as "201301" for the first quarter of 2013.
YYYY_QQ
Creates a dimension slice with a value of one quarter, such as January 01, 2013-March 31, 2013. If you use the YYYY_QQ formula, you must name the dimension slices for the dimension in the YYYY_QQ format, such as "2013_01" for the first quarter of 2013.
