Graph databases are no longer the new guy on the block. They continue to move into mainstream enterprise operations and some big name vendors are making their mark. This interesting news came to us from DATAVERSITY in their article, “Enterprises Move to Graph Databases.”

Oracle and Teradata are both examples of major companies that have implemented graph capabilities on top of existing relational technology. IBM and Informatica are using third-party graph technology in their products.

A graph database is a database that uses graph structures for semantic queries with nodes, edges and properties to represent and store data. The graph directly relates data items in the store. The relationships allow data in the store to be linked together directly, and in many cases retrieved with a single operation.

This is different from conventional relational databases, where links between data are stored in the data itself, and queries search for this data within the store and use the JOIN concept to collect the related data.
