Functional querying in graph databases [PDF]

open access: yesVietnam 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

Modelling of Graph Databases

open access: yesJournal of Advanced Engineering and Computation, 2017
Comparing graph databases with traditional,e.g., relational databases, some important database features are often missing there. Particularly, a graph database schema including integrity constraints is mostly not explicitly defined, also a conceptual ...

A graph database for persistent identifiers

open access: yes, 2019
The Handle Software manages references to resources of information. However, it does not support a search functionality. A prior implementation with Elasticsearch could not efficiently capture the complex structure of our dataset, especially the relationships between handles.

Neural Graph Databases

open access: yesCoRR, 2022
Graph databases (GDBs) enable processing and analysis of unstructured, complex, rich, and usually vast graph datasets. Despite the large significance of GDBs in both academia and industry, little effort has been made into integrating them with the predictive power of graph neural networks (GNNs).

Semantic acyclicity on graph databases [PDF]

open access: yesProceedings of the 32nd ACM SIGMOD-SIGACT-SIGAI symposium on Principles of database systems, 2013
Summary: It is known that unions of acyclic conjunctive queries (CQs) can be evaluated in linear time, as opposed to arbitrary CQs, for which the evaluation problem is NP-complete. It follows from techniques in the area of constraint-satisfaction problems that semantically acyclic unions of CQs -- i.e., unions of CQs that are equivalent to a union of ...

Development of a knowledge graph framework to ease and empower translational approaches in plant research: a use-case on grain legumes

open access: yesFrontiers in Artificial Intelligence, 2023
While the continuing decline in genotyping and sequencing costs has largely benefited plant research, some key species for meeting the challenges of agriculture remain mostly understudied.

A Graph Rewriting Visual Language for Database Programming [PDF]

open access: yes, 1997
Textual database programming languages are computationally complete, but have the disadvantage of giving the user a non-intuitive view of the database information that is being manipulated.
