Final Report: GSoC '24

Student: Alyaa Mamoon
Organization: Polypheny
Mentors: Marc Hennemann, Marco Vogt
Project: Project Proposal

Project Overview

During the GSoC '24 program, I focused on improving the test coverage for the Cypher query language in Polypheny, covering as many features as possible as described in the Polypheny documentation. This enhancement ensures a more robust implementation of Cypher within Polypheny.
