Graph databases are a part of Oracle’s converged database offering that store and navigate relationships between entities. Oracle provides support for both property and RDF knowledge graphs and simplifies the process of modeling relational data as graph structures. Interactive graph queries can run directly on graph data in the database or in a high-performance in-memory graph server. Oracle Graph Server and Client enables developers, analysts, and data scientists to use graphs within Oracle Database, while Graph Studio in Oracle Autonomous Database removes barriers to entry by automating complicated setup and management, making data integration seamless, and by providing step-by-step examples for getting started.
This library offers a customizable layout for the visualization, as well as for vertex and edge appearance. For example, the highlight and expand vertices functionalities that is available in the graph visualization tool, is also available using this library, but using an API, rather than a UI.
The previous version of PGX.ML supported models for vertices and graphlets. As of this release, we now support a Supervised Edge Wise model, which allows us to run tasks on edges. Using this model, you can now run classification, regression, and embedding generation on edges. In our benchmark assessments, we have also shown up to 13x faster performance than our competitors. This feature will soon be available in Graph Studio.
GraphSON is the JSON based format, used to describe graph data. In this release, we added a new API, for Python and Java, that can be used to import local GraphSON v3.0 files into Oracle Database. This API imports data in batches and generates a CREATE PROPERTY GRAPH statement and applies it. The GraphSON importer also allows you to specify the output graph model that you need, such as PG_VIEW.
Graph visualization in the RDF Server and Query UI now uses Cytoscape.js. Cytoscape is an open sourced, general platform for complex network analysis and visualization. Developers can use popular Cytoscape features to visualize RDF graph query results.
