Session Goal

The main goal of this session was to enhance the data retrieval and processing workflows by updating scripts and proposing modular architectures.

Key Activities

  • Updated a script for data retrieval to access a new domain and structure, eliminating the need for HTML scraping. This involved verifying URLs and organizing downloadable files into categories.
  • Proposed a modular architecture for a linear exploratory notebook to improve reusability, reproducibility, and maintainability.
  • Developed scripts for automation, focusing on downloading files, extracting ZIPs, and exporting data from SQLite to CSV.
  • Evaluated the download.py script for adherence to the Single Responsibility Principle, enhancing modularity.
  • Compared zip extraction scripts to highlight improvements in modularity and batch processing capabilities.
  • Reviewed and validated scripts for exporting SQLite data to CSV, ensuring functionality replication and suggesting improvements.
  • Detailed an automated pipeline for maintaining a local copy of a time series dataset using GitHub Actions.

Achievements

  • Successfully updated and evaluated multiple scripts, ensuring they adhere to best practices in modularity and clarity.
  • Proposed effective strategies for refactoring and automating data processing workflows.

Pending Tasks

  • Implement the proposed modular architecture for the exploratory notebook.
  • Further refine and test the automated pipeline for time series datasets.

Outcome

The session resulted in a comprehensive set of updated and new scripts that enhance the efficiency and maintainability of data retrieval and processing tasks.
