back end

A back-end database is a database that is accessed by users indirectly through an external application rather than by application programming stored within the database itself or by low level manipulation of the data (e.g. through SQL commands).
A back-end database stores data but does not include end-user application elements such as stored queries, forms, macros or reports.
The back-end database concept was invented by Microsoft in 1989.
