Variability-aware data migration tool

Abstract

Relational databases are widely present in the development of software applications. A typical implementation can be seen in content management systems found on most websites. However, the migration of database structure and content between different management systems is not trivial, and the manual creation of scripts makes it difficult to reuse them in other scenarios. This paper presents a tool for database migration by modeling what we call a migration product line. This tool allows to obtain different configurations resulting in final products in a semi-automatic way, i.e., products according to software requirements, considering the variability between any two relational databases. To study the feasibility of our proposal, we have implemented a proof of concept that performs the migration between two databases.
