A Comparison between a relational and a graph database in the context of a recommendation system

This paper presents a comparison between relational and graph database systems' performance in a web application recommendation system. The comparison is conducted on five different queries starting with simple ones, leading up to more complex queries, that are performed in a typical web social application. The implementation is done in C# using .NET framework and the database systems used are SQL Server and Neo4J. To effectively test the performance of both graph and relational database systems, tests were performed on 4 data sets. The tests imply performing 5 different retrieval queries taken in order of difficulty both in SQL and Neo4J.
