MarkLogic Data Hub Service and MarkLogic Server
MarkLogic Server is a multi-model database that can be used to store documents (including JSON, XML and flat text documents), relational data via tables, rows and columns, and graph data.
MarkLogic Server’s greatest selling point is undoubtedly the data agility that users get because it is multi-model and has schema flexibility. Being able to leverage graph, relational and document data interchangeably allows you to choose the right tool for the right job, and moreover, leveraging them in combination can create a solution that is more than the sum of its parts. Leveraging documents inside of graphs, and triples inside of documents, are particularly strong examples of this.
