Title: Data Virtualization Author: Kriko Published: May 30, 2023 Last modified: Jul 7, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. D Letter # Data Virtualization **[Data](https://kriko.io/services/data-analysis-insight) virtualization** is a [data](https://kriko.io/services/data-analysis-insight) management approach that enables users to access information stored across different sources without physically transferring it into a single storage environment. It presents information from databases, [data](https://kriko.io/services/data-analysis-insight) warehouses, cloud platforms, applications and file systems through a unified logical view. The primary purpose of [data](https://kriko.io/services/data-analysis-insight) virtualization is to provide faster and more centralised access to information distributed across multiple systems. Users can retrieve the [data](https://kriko.io/services/data-analysis-insight) they need without having to know where it is physically stored or how the underlying system is structured. This approach can reduce the need to copy [data](https://kriko.io/services/data-analysis-insight) continuously or transfer it between separate storage environments. As a result, ** [data](https://kriko.io/services/data-analysis-insight) integration** processes can become more flexible and manageable. [Data](https://kriko.io/services/data-analysis-insight) virtualization allows multiple users, departments and applications to access the same [data](https://kriko.io/services/data-analysis-insight) sources simultaneously. Authorisation and access controls can ensure that each user only accesses the information required for their responsibilities. A central access layer can also help organisations apply security and [data](https://kriko.io/services/data-analysis-insight) governance rules more consistently. However, overall performance depends on factors such as source-system capacity, network connectivity and query complexity. Industries that generate large volumes of data, including financial services, healthcare, e-commerce, automotive and telecommunications, can benefit from data virtualization. For example, an e-commerce company may analyse website activity, order records, inventory information and customer service data through a single virtual view. This allows information stored in separate systems to be evaluated together and provides a more comprehensive understanding of customer behaviour. The resulting insights can support marketing, inventory management, product development and customer experience initiatives. The data virtualization process begins by identifying the data sources that need to be accessed. Connections are then established, and relationships between different fields and datasets are defined. The data is presented through a common model that authorised users can query and analyse. Access permissions, security rules, data quality controls and performance requirements are configured during the final stage. Using real data securely within testing and development environments is a separate process from data virtualization. Methods such as **data masking**, anonymisation and synthetic data generation are more appropriate for this purpose. Personal, unique or sensitive information can be concealed to create secure datasets that preserve the characteristics of the original data. This enables software testing, performance assessments and analytical work to be carried out without exposing confidential information. Data virtualization may be used together with data masking or synthetic data methods within the same project. However, data virtualization provides a common access layer across different sources rather than creating virtual copies of the information. Data masking and synthetic data generation focus on transforming real information into secure test datasets. Understanding this distinction is important when selecting the appropriate data management method. As data volumes and the number of data sources continue to increase, data virtualization is becoming more important. It can help organisations access information stored across different systems more quickly and reduce unnecessary data duplication. It may also support lower data transfer costs and the development of a more flexible analytics infrastructure. When implemented effectively, it can help organisations make **data-driven decisions** and develop new business strategies. ## Discover it in the dictionary ### Target Market Target market refers to the specific market segment with commercial potential to which a company plans to offer its products or services.
