Service-Oriented Dynamic Evolution Model

To make software system adapt the change of user´s demand, the environmental variation in running period and to make the software system better satisfy user´s application request, a service-oriented dynamic evolution model named SOEM model is proposed in this article. Firstly, based on analyses existing evolution method, introduce the SOA to software evolution. Then give the formal description of a series of concept in service-oriented software evolution process. Define the ruler of service-oriented evolution and the process that based on this evolution ruler. Finally apply SOEM model in a process management system and it has proved that this model has the good ability of evolution.
