Automated Migration of Hierarchical Data to Relational Tables using Programming-by-Example

Summary: Mitra synthesizes XML/JSON-to-relational transformations from small input–output examples. Its key novelty is decomposing synthesis into column and row construction to discover hidden node relationships, achieving 94% benchmark and all real-dataset successes.
