Business Process Modeling with Services

Reverse engineering techniques have become very important within the maintenance process providing several benefits. They retrieve abstract representations that not only facilitate the comprehension of legacy systems but also refactor these representations. Business process archaeology has emerged as a set of techniques and tools to recover business processes from source code and to preserve the existing business functions and rules buried in legacy source code. This chapter presents a reverse engineering process and a tool to retrieve services from running databases. These services are further reused in composing business processes with respect to Service-Oriented Architecture, a new architectural style that promotes agility.
