Abstract

A refactoring of application persistent objects affects not only the source code but the stored data as well. The change is usually processed in two steps: refactoring and data migration, which is ineffective and error prone. We provide a formal model for solution which is capable to migrate database according to a refactoring in the application code. The feasibility of the change and its data-secure processing is addressed as well.

Key words

code refactoring, relational schema evolution, formal model
