Abstract :
A modernization method based on tollgate model is a kind of legacy system modernization by means of service oriented architecture (SOA). On the basis of reverse engineering on the legacy system, we can wrap the slices of the target system into a few services according to certain granularity; the small granularity services or the large granularity services which are composed of the small ones and unwrapped parts will be provided after the encapsulation of the legacy systempsilas code on business level. These services can be mapped to the enterprisepsilas small or large business processes. So we can state that the granularity of services which are derived from the legacy system is variable. After the transformation of legacy system, its service set can be described in a blueprint.
