One of the greatest strengths of graph databases is their ability to treat “relationships” between the data as being as important as the data itself. They show a visual image of a graph in response to queries. Graph databases are designed to hold data without restricting it to a fixed, predetermined model. As a consequence, graph databases are very good at managing complex research queries.
Using a query and a starting point, graph databases search the surrounding data — collecting and accumulating information from thousands of nodes and relationships — while leaving any data outside of the search perimeter alone.
