🏷️ Labels: Data Analysis, Validation, REDATAM, RBFX, Encryption, Github
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The session aimed to provide a comprehensive overview and plan for data analysis, focusing on data integrity, validation, and the handling of specific file formats such as REDATAM and RBFX.

Key Activities

  • Reviewed the project plan, assumptions, and fragile points related to data analysis and validation methods.
  • Reflected on technical and operational findings regarding compressed files and data structures, ensuring traceability and reproducibility.
  • Conducted search queries on GitHub for issues related to REDATAM and RBFX, exploring project details and file formats.
  • Analyzed the structure and characteristics of RXDB and RBFX files, validating hypotheses about encrypted Parquet formats.
  • Evaluated Redatam SPC syntax and export queries for microdata handling.
  • Assessed the feasibility of accessing atomic records in AES-256 encrypted RBFX files, considering runtime and API limitations.

Achievements

  • Established a reproducible path for data analysis and validation, including criteria for scaling a bit-unpacker.
  • Identified useful tools and operational decisions for ensuring data analysis traceability.
  • Proposed concrete actions to validate information and adjust the work plan.

Pending Tasks

  • Further research and analysis on RBFX file format and REDATAM parquet encryption to solidify findings and operational plans.
