Use Data Virtualization to create a virtual table to segment or combine data from one or more tables. Data Virtualization connects multiple data sources into a single self-balancing collection of data sources or databases.
The Data Virtualization service is a part of the data fabric.
Overview
- Required service
- Data Virtualization.
You must create and deploy a service instance of Data Virtualization in Cloud Pak for Data as a Service to virtualize your data. For more information, see Provision a service instance for Data Virtualization.
After you provision your service instance, you can set up your Data Virtualization instance. For more information, see Getting started with Cloud Pak for Data as a Service and Quick start: Virtualize data.
