Creating virtual objects in Data Virtualization

Last updated: Nov 26, 2024

You can use the Data Virtualization service to create virtual objects from various data sources so that you can query and use the data as if it came from a single source. Data Virtualization supports creating a virtual object from a single table, from multiple tables, or from files. You can also create a join view from multiple virtualized tables.

About this task

The Data Virtualization service provides multiple methods to create virtual objects:

Create a virtualized table from a single data source.
Create a virtualized table from multiple data sources.
Creating a virtualized table from files in cloud object storage.
Join virtual objects to create a join view.

When you create virtual objects, it is important to gather statistics for the objects to ensure good query performance. For more information, see Improving query performance in Data Virtualization.
