Описание тега linked-tables
Linked-tables are tables that are joined from different data sources.
Example- creating a query in access that joins the access table with data from sql-server.
A linked server allows for access to distributed, heterogeneous queries against OLE DB data sources. After a linked server is created, distributed queries can be run against this server, and queries can join tables from more than one data source.
These tables when joined from two different data sources are called linked-tables.
