🏷️ Labels: Python, DBF, CSV, CLI, Data Extraction
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The session aimed to develop a comprehensive tool for extracting DBF files and converting them into CSV format, along with implementing a command-line interface for managing data extraction tasks.

Key Activities

  • Developed a Python script for extracting DBF files from specified input directories, applying optional column exclusions, and generating corresponding CSV files in organized output directories.
  • Implemented the extract_dbf_to_csv function in extractor.py, enabling recursive directory traversal and file classification.
  • Completed the scaffold for extractor.py, integrating logic for DBF to CSV conversion and export functionality.
  • Created a command-line interface (CLI) for the eph-extractor, including commands for fetching, extracting, and verifying data from the EPH dataset.

Achievements

  • Successfully developed and integrated the DBF to CSV extraction script and CLI tool.
  • Completed the scaffold for extractor.py with logic for recursive directory traversal and export functionality.

Pending Tasks

  • Add unit tests to ensure the functionality of the extractor.
  • Complete the implementation of validator.py and metadata.py.
  • Adjust the CLI to accommodate new functionalities.
