This chapter delves into the drivers that require the support of multiple versions of data—even when the data may conflict with the ideals of an SVOT.
Managing multiple versions provides improved capabilities to support the needs of the organization and to provide the necessary contexts for solving business problems using AI, in both operational and analytical environments. The awareness ...
