Neo Technology Commercializes Next Generation Graph Based Database
A new generation of database products and companies is beginning to emerge, and one of the more interesting examples is Swedish-based Neo Technology, the developer and vendor of the neo4j graph based database (graph in the data structure sense). The neo4j product has been in development for over 8 years, and Neo Technology are today announcing a new $2.5M round of funding. The company has been developing the neo4j project as a commercial product, and is now taking it to market with a dual-license model.
A graph database is a more natural method for expressing, storing and retrieving data that does not fit well in a standard relational database schema. The best example is to consider social networking
In a demo of the product we saw, a mock social network structure was created where 1,000 users were defined, each with 50 friends. The traditional table based database took 2,000ms to query every friend from every user, while the graph-based neo4j database took 2ms. To demonstrate the efficiency of the database further, with 1,000 times more users at a million (and an order of magnitude magnitude more connections), the total query time was still 2ms. The graph model and the neo4j database are able to easily scale with complex relationships between entities and with a more flexible schema.
