Virtualizing data (Data Virtualization)
The most common mechanism for virtualizing data is to create a table "view" or virtual table. You can create a virtual table to segment or combine data from one or more tables.

Service This service is not available by default. An administrator must install this service on the IBM Cloud Pak for Data platform.

Tables that are similar from multiple sources can be combined into a single virtual table, which creates a unified definition containing the columns and data from all participating data sources. Segmentation is vertical (either a subset or superset of columns based on a selection of chosen columns). You can then run queries against the resulting virtual table no different than how you would query any of the base tables.
