Longitudinal Research Sample Tracking System

research tracking sample management recursive queries data provenance
Prompt
Develop a robust PostgreSQL database schema and accompanying analytical queries to track longitudinal scientific research samples across multiple studies. Implement recursive common table expressions (CTEs) to trace sample lineage, create audit trails for sample transformations, and generate comprehensive provenance reports. Include mechanisms for handling sample splitting, merging, and cross-referencing between different research projects.
