Data Warehousing Questions
Data virtualization in data warehousing refers to the process of creating a virtual layer that allows users to access and query data from multiple sources without physically moving or replicating the data. It involves integrating data from various sources, such as databases, data lakes, and cloud platforms, and presenting it to users as a single, unified view. This virtualization layer provides a centralized and consistent view of the data, enabling users to easily access and analyze information without the need for complex data integration processes.
