Bottom-up Change Specification and Change Model
Modeling changes offers sufficient formalization required by change management in LCSs. Changes have been modeled using various tools and technologies . For example, the Z language has been used to reflect changes in database schema . However, changes to Web services are fundamentally different from changes in databases. Web services consist of behavioral aspects that are not relevant to data. In this chapter, we first propose a taxonomy of bottom-up changes. This allows us to define specific strategies to be applied to different types of changes. Based on the taxonomy, we then propose a formal model of bottom-up changes.
