DB Mining

This repository contains the data, source code, and replication material for a research project on the use of database management systems (DBMSs) in open-source Java projects. The project currently supports two complementary empirical studies: one on DBMS adoption and interaction, and another on vulnerabilities in DBMS-related libraries.

Studies

Study 1 — DBMS Adoption and Interaction

Analyzing the Adoption and Interaction of Database Management Systems Throughout the History of Open Source Projects

This study investigates which DBMS technologies are used by open-source Java projects, how their adoption evolves throughout project histories, and how different DBMS technologies are combined. It includes current and historical analyses of DBMS usage, implementation technologies, query mechanisms, co-occurrence, and replacement patterns.

See README_ADOPTION.md for the study description, pipeline, installation instructions, datasets, and reproduction steps.

Study 2 — Vulnerabilities in DBMS-Related Libraries

Analyzing Vulnerabilities of Database Management System Libraries in the History of Open Source Java Projects

This study reconstructs Maven dependency histories to investigate vulnerable DBMS-related library releases, vulnerability propagation, downstream project exposure, disclosure and resolution phases, post-resolution exposure duration, and the motivations behind dependency updates.

See README_VULNERABILITIES.md for the complete method, research questions, data sources, temporal definitions, and reproduction steps.

Repository Organization

Both studies share part of the project corpus and research infrastructure, but their analysis pipelines and derived results are documented separately. Before running an analysis, follow the requirements and commands in the corresponding study README.
