Overview
Data Virtualization creates a virtual layer between data sources and the users/applications that need the data. It provides a unified view of data from multiple, heterogeneous sources (databases, files, cloud services) in real-time, without the need to physically move or replicate the data (unlike ETL).
Benefits
- Agility: Faster access to new data sources.
- Cost Savings: Reduced storage and processing costs associated with data replication.
- Real-time Access: Users see the most up-to-date data from the source.
- Simplified Governance: Centralized security and access control.
Use Cases
- Logical Data Warehousing
- Real-time BI and Reporting
- Master Data Management
