Please don't confuse a graph data structure with a "visual" graphical representation, graphical can mean anything.
Graphs are nodes and relationships to other nodes which all can have relationships. For you as a Java developer it is perhaps easiest to imagine those as object networks. Otherwise it is as with every other Database, you have a physical database and an API, you create your data as you do with any other technology, by inserting things (and in a graph additionally by relating things). Perhaps one or more of the presentations about graph databases is useful for you. http://www.slideshare.net/tag/neo4j http://www.slideshare.net/emileifrem/an-intro-to-neo4j-and-some-use-cases-jfokus-2011 http://www.slideshare.net/peterneubauer/gdm-2011-neo4j-and-real-world-apps http://www.springsource.com/downloads/getting-started-spring-data-graph Cheers Michael You might also look into the documentation of our Spring Integration Library (Spring Data Graph) - http://bit.ly/sdg-book Am 02.05.2011 um 19:07 schrieb Anil Tatikonda: > Thanks a lot for all the Help. > > Yes I'm a Java Developer i may sound so dumb to you.
