Neo4j vs TerminusDB: What are the differences?

<Neo4j is a native graph database while TerminusDB is a native graph database with strong versioning capabilities. Both databases are used for managing and querying graph data in different ways. In this comparison, we will highlight key differences between Neo4j and TerminusDB.>

1. Data Model: Neo4j uses a property graph data model where nodes and relationships can have properties, while TerminusDB uses a resource description framework (RDF) data model that represents data as subject-predicate-object triples.

2. Versioning: TerminusDB has built-in version control features that allow users to track changes and history of data, making it suitable for collaborative environments, whereas Neo4j lacks native versioning capabilities.

3. Collaboration: TerminusDB is designed for collaborative work with support for branching, merging, and sharing data projects among multiple users, which is not a core feature in Neo4j.

4. License: Neo4j uses a dual licensing model where the community edition is open source under the GPL v3 license, but TerminusDB is fully open source under the GNU Affero General Public License (AGPL) v3.

5. Query Language: Neo4j primarily uses the Cypher query language for data retrieval and manipulation, while TerminusDB supports SPARQL for querying RDF data along with WOQL (Web Object Query Language) for querying its data model.

6. Scalability: Neo4j offers horizontal scalability through clustering for distributed systems, whereas TerminusDB is focused on providing data integrity and versioning features but may have limitations in scaling for massive datasets.

In Summary, Neo4j and TerminusDB differ in terms of data model, versioning capabilities, collaboration features, licensing, query languages, and scalability.
