Abstract:

Database applications need to undergo schema refactorings during their life cycle. Such refactorings require migrating the underlying data to a new database and re-implementing large chunks of the code that query and update the database. These code and data migration tasks are typically non-trivial and error-prone to developers. This talk presents program synthesis techniques to help developers correctly and easily evolve database applications. Specifically, it first presents a novel technique that can automatically synthesize an equivalent version of the database program operating over the new schema. Then it describes a synthesis technique that helps developers migrate data between schemas using input-output examples. The experimental results demonstrate that these techniques are effective for code and data migration during schema refactoring, and they are more efficient than several baselines and state-of-the-art approaches.
