Wrapping coarse-grained objects using standard infrastructure technology

There are two approaches to migrate a particular subsystem: reengineering and wrapping. Wrapping is the most effective strategy for software migration if the legacy system is decomposed into a few large chunks where the number of communication paths among subsystems are minimized. Software engineers use standard infrastructure technologies for coarse-grained objects with better software reuse and interoperability. Wrapping applications or subsystems with standard or accepted technolgies has advantages which include platform independence and opportunities for reuse. Once subsystems are entombed using standard wrappers, maintainers can safely ignore the details inside them and can focus on the communication patterns among the subsystems.
