🕒 19:20–19:35
🏷️ 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.
