FOREIGN TABLE Meaning and
Definition
-
A foreign table refers to a table in a database management system (DBMS) that is not located in the same database as the query being executed. In other words, it is a table that exists in an external database or a remote server. A foreign table is accessed and queried through a process called remote access or remote data access.
Foreign tables are used to establish connections between two or more databases, allowing data to be retrieved or manipulated across different database systems. This functionality is particularly beneficial in complex environments where data needs to be consolidated or shared across multiple databases.
To access a foreign table, the DBMS needs to establish a connection with the external database or server. It does this by using specific connection parameters such as the database name, server address, username, and password. Once the connection is established, the DBMS can then execute queries on the foreign table as if it were a local table, retrieving or modifying data as required.
The concept of foreign tables is commonly employed in relational database systems that support distributed databases or data integration. It enables seamless data access and integration across disparate databases, providing a unified view of the data stored in different locations. Foreign tables contribute to the interoperability and flexibility of the database system, facilitating efficient and convenient data management across heterogeneous database environments.

Etymology of FOREIGN TABLE
The etymology of the phrase "foreign table" can be traced back to the Middle English word "forain" or "forein", which means "outside" or "from outside". It was derived from the Old French word "forain", meaning "external" or "from abroad". Over time, the term evolved to refer to something that is not native or domestic. The word "table" in this context simply refers to a flat surface used for various purposes, such as dining or working.
