A method for web application data migration based on RESTful API: A case study of ezScrum

As a web application evolves, it tends to adopt a mixture of different ways of storing persistent data. This often discourages users from upgrading from an older version to a newer version if the data schemas are different. To tackle this problem, we have developed a RESTful API-based data migration method for embedding ETL (extract-translate-load) features into web applications. The proposed RESTful API-based method has been applied to migrating data for ezScrum, a web application for Scrum support.
