code/

This folder contains the source code used for:

• Crawling GitHub pull request (PR) data from 15 selected VDBMS repositories.
• Filtering and preprocessing PRs to identify bug-related commits.

Each script is annotated with usage instructions and designed for reproducibility.

data/

This folder includes:

• 15 subfolders (one per VDBMS), each containing the filtered PR data corresponding to that system.
• A master Excel file VDBMS.xlsx, which contains:
  • Our taxonomy of bug symptoms, aspects (root causes), and fix strategies.
  • The aggregated classification results for all systems.

pic-in-paper/

This folder stores supplementary figures that could not be included in the main body of the paper due to space constraints. These figures are referenced in the paper and are essential for readers who wish to explore detailed visual analysis.
