Late binding

In computing and information science, late binding is a paradigm in which a user knows only the name of something but not its location; the user need not be aware if information moves from one computer to another, because the database will be updated along with the move so that people can always find the address when it's needed. DNS, introduced into the internet in 1983, is an early and successful implementation of this concept. Since the 1990's, late binding has been often used in compilers for programming languages and linkers which load programs in a computers memory before and during their execution. Library science has embodied the concept in its Digital Object Identifier (DOI) standard for looking up publications online.
