Abstract

U ovom radu predstavljena je problematika hijerarhije među podatcima. Uz to objašnjeni su najčešći modeli ostvarivanje hijerarhije u SQL domeni relacijskih baza te također u domeni NOSQL-a na modelu grafa. U radu su uspoređeni navedeni modeli prema zahtjevima kompleksnosti pisanja upita, vizualizaciji te težini implementacije.
Kroz rad napravili smo uvod u Neo4j grafičku bazu podataka te u Cypher upitni jezik.
Kroz radni okvir SpringBoot napravljena je integracija Neo4j baze podataka s postojećim projektom IoT-Polje i dodatim uslugama koje su razvijene u sklopu projekta R.
Kroz rad razvijeno je hibridno rješenje hijerarhije koje ne ovisi o postojećem dizajnu i implementaciji spremanja podataka. Drugim riječima ostvarili smo rješenje hijerarhije koje se s lakoćom povezuje s postojećom relacijskom bazom podataka.

Abstract (english)

In this paper, the issue of hierarchy among data is presented. In addition, the most common models for realizing hierarchy in the SQL domain of relational databases and also in the domain of NOSQL on the graph model are explained. The paper compares the mentioned models according to the requirements of the complexity of query writing, visualization and the difficulty of implementation.
Through the work, we made an introduction to the Neo4j graphic database and the Cypher query language.
Through the SpringBoot framework, the Neo4j database was integrated with the existing IoT Polje project and additional services, which were developed as part of the R project.
Through the work, a hybrid solution of the hierarchy was developed, which does not depend on the existing design and implementation of data storage. In other words, we have created a hierarchy solution that is easily integrated with existing relational database.
