VIRTUAL DATABASE Meaning and
Definition
-
A virtual database refers to a concept in computer science and database management that involves creating a logical view or representation of a database, which may be stored across different physical locations or systems. It allows users to interact and query data as if it were stored in a single, unified database, irrespective of its physical location.
Virtual databases are typically implemented using database middleware or virtualization technologies. The virtual database layer sits between the applications and the physical databases, providing a uniform interface and access to data sources that may include multiple databases, file systems, web services, or even spreadsheets.
By abstracting the physical storage details, a virtual database enables users to work with data from different sources, as if they were part of a single database. It offers a flexible and efficient way to integrate and aggregate data across disparate systems, providing a consolidated view that simplifies the overall data management process.
Virtual databases provide several benefits, including improved performance, scalability, and availability. They also facilitate data integration, federation, and real-time data access without the need for physical data replication. This approach enhances data agility and allows businesses to effectively leverage their existing data, irrespective of its storage location or format, thereby enabling better decision-making and analysis.

Etymology of VIRTUAL DATABASE
The word "virtual" comes from the Latin word "virtus" meaning "quality" or "excellence". It later evolved to mean "potential" or "possibility". In computing, "virtual" refers to something that is simulated or exists in a non-physical but functional form.
The word "database" is a combination of "data" (plural of "datum" meaning "information") and "base" (referring to a foundation or core). A database is an organized collection of data stored and accessed electronically.
Therefore, the term "virtual database" describes a simulated or non-physical collection of organized electronic data. It typically implies that the database is accessed or used remotely, either through a network or the internet, without requiring direct physical access to the stored data.
