Before you begin: If you use an Oracle database for interaction history, update
the column definitions for DateTime properties to use the TIMESTAMP datatype instead of the
DATE datatype. For more information, see Modifying column definitions to use the TIMESTAMP data type in an Oracle database.
Pega Customer Decision Hub
8.5 adds new interaction history summaries, which are shipped
without preaggregated data. To save processing time, turn on preaggregation for each
interaction history summary by materializing them.
Preaggregated data sets save processing time because they include the latest interactions.
Data sets that are not preaggregated do not include the latest interactions and therefore they
query the database.
