Virtual Database Systems

A Virtual Database System (VDS) is an approach that allows users to access and manage data stored across multiple physical databases as if it were a single, unified database. It provides a layer of abstraction, hiding the complexity of different data sources, formats, and locations. This system enables seamless, centralized access to diverse data without physically consolidating it, improving flexibility and efficiency. Essentially, a VDS simplifies data management by integrating information from various systems so users can retrieve and work with it effortlessly, regardless of how or where the data is stored.
