Ontology Overview
An Ontology is a model that defines semantic relationships between data. In D.Hub, ontologies allow you to connect distributed datasets and build knowledge graphs from a business perspective.
Key Components

1. Entity
An entity is an abstraction of a real-world object (e.g., Customer, Product, Order).
- Each entity can be mapped to a specific dataset.
- Entities have properties that correspond to columns in the dataset.
2. Relationship
A relationship defines associations between entities (e.g., a customer orders a product).
- Relationships have a direction and a type.
- They are stored in a graph database, enabling complex connectivity analysis.
Feature Menu
The Ontology menu is divided into two main features.
Builder
A tool for designing ontology models.
- Visually create and edit entities and relationships.
- Define and manage data schemas.
Graph Explorer
A tool for visually exploring actual data loaded into the defined model.
- Execute Cypher queries to analyze data relationships.
- Click on nodes and edges to view detailed information.
