Graph databases use topographical data models to store data. These databases connect specific data points (nodes) and create relationships (edges) in the form of graphs that can then be pulled by the user with queries. Nodes can represent customers, companies, or any data a company chooses to record. Edges are formed by the database so that relationships between nodes are easily understood by the user. Businesses can utilize graph databases when they are pulling data and do not want to spend time organizing it into distinct relationships. Large enterprises may use complex queries to pull precise and in-depth information regarding their customer and user information or product tracking data, among other uses. Database administrators can scale high data values and still create usable models. Some businesses may choose to run an RDF database, a type of graph database that focuses on retrieving triples, or information organized in a subject-predicate-object relationship. Similar types of databases include document database tools, key-value store tools, object-orientated database tools and more. Developers who are looking for an affordable solution can look to free database software.

Hundreds of billions of facts building the World Knowledge Graph are available in the Linked Open Data cloud. Even more are gathered as Proprietary Data Sets. Graph DB ™ is a semantic graph database that serves organizations to store, organize and manage content in the form of semantically enriched smart data. A non-relational (NoSQL) database, Graph DB handles massive loads, queries, and inferencing in real time. This allows for seamless integration of disparate data silos and a holistic 360-degree view of information. In essence, Graph DB is a “semantic repository”, a database system used for storage, querying, and management of structured data. It uses ontologies to automatically reason about data. Smart data management means better information products and services at a faster speed. This is achieved by handling information in a way that allows data items to be seamlessly mixed, exposed and shared across different platforms. As a result, their relationships mapped with a high level of detail. With Graph DB your data is stored in atomic facts that are easy to classify, reuse, combine share and integrate. Something more, such a mechanism for storing and managing data allows the creation of new facts that are implied in data. How Graph DB Enables Smart Data Management? Data integration and interlinking - The ability to recognize entities across multiple sources hold great promise helping to manage your data more effectively and pinpointing connections in your data that may be masked by slightly different entity references. Single interconnected information space formed by structured data and text documents - Materialised connections between free-flowing, unstructured text, and data facts stored as database entities are extremely valuable. Such connections link entities from the database to the documents that mention them denoting relationships from which they were extracted. Linked Open Data Compatibility - Linked Data is an approach for publishing and interlinking data on the web to improve data interchange. The amount of openly released dataset grows exponentially in the recent years, covering everything from music, places, subjects of interest and products, to highly specific domains as drugs and bibliography. When applied correctly, semantic facts can enhance your knowledge management and data discovery applications. You can answer more queries much faster and the results of the queries are highly relevant to your search. W3C standards compliance - Graph DB stores semantic facts in the form of subject - predicate - object using the Resource Description Framework. RDF is a standard model for data publishing and interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ. Expressive, rich and flexible data model - Graph DB supports all forms of metadata classification of data, express as ontologies, where ontologies are equated but limited to thesauri, taxonomic hierarchies of classes, class definitions and relations. Reasoning - Graph DB can infer new knowledge from existing facts. This is called inferencing. Why is this important? You can create new facts from existing facts. Your queries run faster. Your results are more accurate. Not all graph databases support this capability and some apply different techniques to infer new semantic facts. The applications of inferencing span industries and use cases.
