Pattern 16.12 Object Locality and Link Implementation

Pattern 16.12, Object Locality and Link Implementation Locality of an object— where it resides and executes—can be decided independently of basic design, employing appropriate patterns to implement links and messages crossing locality... 

Software location also tracks business location. Distribution of the objects among hosts comes after and is independent of object design (see Pattern 16.12, Object Locality and Link Implementation). This applies whether there is a central server or several servers or whether the business objects are hosted on server machines or clients or in their own machines. The strength of this independence is that the hosting can easily be rearranged— dynamically, if appropriate—as people and departments are relocated. 

Decide Distribution. That is, where does each object reside On which machine On what storage medium In which major component This can be done independently of the design. See Pattern 16.12, Object Locality and Link Implementation.
