What Is Data Virtualization?
Data Virtualization is an advanced approach to data integration. It is an easier way to integrate, federate, and transform data from multiple data sources into a single, unified environment in real-time. With Data Virtualization, you’re not just collecting different data sources (such as ETL, ESB, and other middleware) but connecting them and leveraging existing Data Warehouse, Big Data lakes, or different data infrastructures already in place.
Therefore, Data Virtualization has the ability to provide a holistic view of business operations and quickly help identify new value possibilities. Please note, the data can easily be accessed or shared by other applications, without replicating the data through the “virtual” metadata layer.
