TL;DR

This guide compares 7 data virtualization tools for querying across systems without copying data.

Enterprise platforms: Denodo and TIBCO Data Virtualization are the established options for federated access across large estates.
Open source: Red Hat JBoss and Teiid provide virtualization without licence cost, given engineering capacity to run them.
Specialist: AtScale serves a semantic layer for BI, Cdata focuses on live connectivity, and Accelario targets test data provisioning.
The trade-off: virtualization avoids duplication but leaves query performance dependent on the underlying sources. Many teams pair it with a warehouse for heavy workloads.

Data virtualization tools let you query data across siloed systems without physically copying it first, which removes a whole layer of movement and duplication. Traditional approaches answer the same need with complex pipelines, redundant copies and delay, and each of those adds cost and room for error. The seven tools below take that federated approach, with different trade-offs in performance and governance.

However, there’s a solution to these problems—data virtualization. It enables you to abstract and integrate data from multiple data sources without physically copying or moving it. By creating a virtual layer, data virtualization empowers your organization with enhanced data integration, efficient data access, and improved data analysis.

Let's dive into some of the popular data virtualization tools, along with their key features.

What is Data Virtualization?

Data virtualization is a modern data management approach that creates an abstract layer of data. This layer acts as an intermediary, allowing you to access data from multiple sources without knowing the exact location or structure of this data. It creates a combined view of data from various different sources, giving the appearance of complete data stored in a centralized location.

By implementing data virtualization, you can seamlessly integrate your data from various sources, including databases, cloud storage systems, and other data platforms. This eliminates the need to worry about the different structures and formats of data in each source, saving significant time and effort.

What are Data Virtualization Tools?

Data virtualization tools are applications that allow you to implement this approach, providing the functionality to manage and interact with the virtualized data layer. Some major benefits of using data virtualization tools are mentioned below:

Faster Data Access: By utilizing data virtualization tools, you can access and query data instantly from diverse sources without physically relocating it. This ensures agility and helps faster decision-making.‍
Reduced Redundancy: By creating a virtual layer, the data virtualization tools minimize the need for creating duplicate copies of data, reducing the costs of storage. This helps ensure the accuracy and consistency of the processed data.‍
Convenient Data Migration: When you are switching to new systems or upgrading the infrastructure of the existing systems, these data virtualization tools enable you to streamline the data migration. The abstraction layer acts as a bridge between the old and the new data sources, minimizing disruption and downtime.‍
Faster Development: Data virtualization tools enable you to access and integrate data from various sources into their applications without worrying about the underlying infrastructure complexities.
