Introduction
The NCBO-OOR provides server-side flexibility by leveraging the enterprise pattern of "Dependency Injection." This is accomplished by applying the Spring technology which enables a partner to insert any software implementation that abides to the NCBO-defined interfaces purely by configuration. In other words, a different implementation can be deployed without a recompile or rebuild of the entire NCBO-OOR code-base.

BioPortal Server-Side Pattern: Dependency Injection
The gist of dependency injection is that a seperate object, an assembler, populates the implementation of a defined interface that can be used by any consuming object that understands the interface. Spring which implements a specific variation of this patterns called "Setter Injection." A significant number of BioPortal server-side capabilities heavily leverage this pattern. The benefit of this approach all these capabilities can be swapped out with different implementations. To learn more about this pattern, please see [Martin Fowler's excellent exposition on this topic | http://martinfowler.com/articles/injection.html].
