Replication Data for: DIFFBASE: A Differential Factbase for Effective Software Evolution Management
Xiuheng Wu, Chenguang Zhu, Yi Li · 2021
Numerous tools and techniques have been developed to extract and analyze information from software development artifacts. Yet, there is a lack of effective method to process, store, and exchange information among different analyses. DiffBase provides a uniform exchangeable representation supporting efficient querying and manipulation, based on the existing concept of program facts. We consider program changes as first-class objects, which establish links between intra-version facts of single program snapshots and provide insights on how certain artifacts evolve over time via inter-version facts. DiffBase includes a series of differential fact extractors and multiple software evolution management tasks have been implemented with DiffBase, demonstrating its usefulness and efficiency.
