Opent Native Graph Database (ONgDB): What Is It Really?

What is a Graph Database - ONgDB is a fully open source scalable native graph databaseI often get the question, what is a graph database. A graph database, or otherwise known as “graph-oriented database,” is a particular form of NoSQL database that makes use of a graph structure consisting of nodes and edges to query, house, and map out relationships. It consists of databases which specifically serve to store data structures that are highly connected.

A graph database is an example of a storage solution that shows where linked elements are connected to each other in the absence of an index. Groups of a specific entity can be accessed by means of dereferencing a pointer.

There are various kinds of graphs that can be stored. They can range from a single undirected graph to property graphs to hyper-graphs.

A graph DB usually meets the following requirements:

Storage is specifically arranged for the data to be represented as a graph, with provisions made for housing edges and vertices.
Storage is tweaked for graph transversal without making use of an index when following edges.
The storage format is arranged so queries leverage proximity data beginning from a single or multiple root nodes, as opposed to global queries.
A data model that is flexible for certain solutions: without having the need to declare data for edges or vertices, instead of a table-oriented model of database.
Has an integrated API along with entry points for further algorithms of graph theory.

ONgDB is an example of a scalable and reliable graph database kept free and open by the Graph Foundation. It is a native implementation that avoids using indexes for traversal, and supports the now open graph query language called Geequel.

Currently, ONgDB is growing in popularity and used globally, with years of production and thousands of deployments in startups to Fortune 500 companies.

Reasons why ONgDB is so popular is due to its:

Strength: all transactions being made are completely ACID
Swiftness: graph transversal is quick with a depth of 1,000 levels in just milliseconds
Scalability: graph storage of billions of elements in a single machine

Many choose to deploy ONgDB for the GraphGrid Cloud since it’s the fastest and highly scalable native graph database in the world. The advantages that ONgDB offers in modeling connected data are impeccable and allows for tackling problems that couldn’t be resolved with typical databases.
