Comparative Evidence on the Performance of Programming Languages and Frameworks for Back-End Development: A PRISMA-Based Systematic Literature Review: Supplementary Materials

This record contains the supplementary materials for the study entitled “Comparative Evidence on the Performance of Programming Languages and Frameworks for Back-End Development: A PRISMA-Based Systematic Literature Review”. The package contains the PRISMA-based study-selection flow, master matrix, screening and eligibility records, quality-assessment results, research-question extraction files, machine-readable CSV datasets, data dictionary, methodology, provenance information, file inventory, integrity checks, and the PRISMA flow diagram. The final study corpus comprises 15 primary studies evaluating programming languages, frameworks, platforms, experimental settings, performance metrics, comparative findings, and methodological limitations related to back-end development. The materials are provided to support transparency, auditability, reproducibility, and reuse. Full-text copies of the primary studies are not redistributed.
