descriptive

This work attempts to inform the terminology and practice for designing data science (DS) pipeline. Our investigation suggest that DS pipeline is a well used software architecture but often built in ad hoc manner. We demonstrated the importance of standardization and analysis framework for DS pipeline following the traditional software engineering research on software architecture and design patterns. We also contributed three representations of DS pipelines that capture the essence of our subjects in theory, in-the-small, and in-the-large that would facilitate building new DS systems.
