Web application for manipulation of Neo4j database

Fokus ovog rada je opis Neo4j graf baze podataka. U radu su kratko opisane NoSQL baze podataka, odnosno njihova podjela i karakteristike. Više pažnje predano je opisu graf baze podataka te usporedbi iste s relacijskom bazom podataka. Detaljnije je analizirana Neo4j baza podataka i njen upitni jezik Cypher. Na kraju je dan primjer aplikacije kojom je prikazan rad s Neo4j bazom podataka. Graf baze podataka nova su tehnologija koja u nekim karakteristikama prednjači pred relacijskim bazama, no koja ima još uvijek puno prostora za napredak. Cilj ovog rada nije veličati nerelacijske baze podataka u odnosu na relacijske već osvijestiti čitatelja da postoji više modela baze podataka i da svakoj aplikaciji ne odgovara jedan te isti model baze podataka.The focus of this paper is the description of the Neo4j graph database. The paper briefly describes NoSQL databases, ie their division and characteristics. More attention was paid to the description of the graph database and its comparison with the relational database. The Neo4j database and its query language Cypher were analyzed in more detail. Finally, an example of an application showing how to work with the Neo4j database is given. Database graphs are a new technology that is ahead of relational databases in some respects, but still has a lot of room for improvement. The aim of this paper is not to glorify non-relational databases in relation to relational ones, but to make the reader aware that there are several database models and that not one database model corresponds to each application
