Mapping RDF Databases to Property Graph Databases
IEEE Access, 2020 RDF triplestores and property graph databases are two approaches for data management which are based on modeling, storing and querying graph-like data. In spite of such common principle, they present special features that complicate the task of database ...

Storage and Query of Drug Knowledge Graphs Using Distributed Graph Databases: A Case Study [PDF]
BioengineeringBackground: Distributed graph databases are a promising method for storing and conducting complex pathway queries on large-scale drug knowledge graphs to support drug research. However, there is a research gap in evaluating drug knowledge graphs’ storage

Functional querying in graph databases [PDF]
Vietnam Journal of Computer Science, 2017 The paper is focused on a functional querying in graph databases. We consider labelled property graph model and mention also the graph model behind XML databases. An attention is devoted to functional modelling of graph databases both at a conceptual and

Regular Queries on Graph Databases [PDF]
Proceedings of the 32nd ACM SIGMOD-SIGACT-SIGAI symposium on Principles of database systems, 2015 Graph databases are currently one of the most popular paradigms for storing data. One of the key conceptual differences between graph and relational databases is the focus on navigational queries that ask whether some nodes are connected by paths ...

biochem4j: Integrated and extensible biochemical knowledge through graph databases. [PDF]
PLoS ONE, 2017 Biologists and biochemists have at their disposal a number of excellent, publicly available data resources such as UniProt, KEGG, and NCBI Taxonomy, which catalogue biological entities. Despite the usefulness of these resources, they remain fundamentally

Analysing River Systems with Time Series Data Using Path Queries in Graph Databases
ISPRS International Journal of Geo-Information, 2023 Transportation networks are used in many application areas, like traffic control or river monitoring. For this purpose, sensors are placed in strategic points in the network and they send their data to a central location for storage, viewing and analysis.

Context-free path querying with all-path semantics using matrices with sets of intermediate vertices [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2021 The study considers the problem of context-free path querying with all-path query semantics. This problem consists in finding all paths of the graph, the labels on the edges of which form words from the language generated by the input context-free ...

GRAPH DATABASE MANAGEMENT SYSTEMS AND GRAPH THEORY [PDF]
Fourth International Scientific Conference ITEMA Recent Advances in Information Technology, Tourism, Economics, Management and Agriculture, 2020 In recent years, graph databases have become far more important. They have been proven to be an excellent choice for storing and managing large amounts of interconnected data. Since graph databases (GDB) rely on a graph data model based on graph theory, this study examines whether currently available graph database management systems support the ...
