A Grammar for Reproducible and Painless Extract-Transform-Load Operations on Medium Data [article]

Benjamin S. Baumer
2018 arXiv   pre-print
We propose a predictable and pipeable framework for R (the state-of-the-art statistical computing environment) that leverages SQL (the venerable database architecture and query language) to make reproducible  ...  These obstructions hamper thorough peer-review and thus disrupt the forward progress of science.  ...  Raw files downloaded via etl extract() are placed in raw. etl transform() reads those files and writes the resulting transformed files to load.  ...
