I'm using the Batch_Insert example to insert Data into the database

How can i read this data back from the database. I can't find any examples of how i do this.

     public static void CreateData()
     {
      // create the batch inserter
      BatchInserter inserter = new BatchInserterImpl( "var/graphdb", BatchInserterImpl.loadProperties( "var/neo4j.props" ) );

      Map<String,Object> properties = new HashMap<String,Object>();

      properties.put( "name", "Mr. Andersson" );
      properties.put( "age", 29 );
      long node1 = inserter.createNode( properties );

      properties.put( "name", "Trinity" );
      properties.remove( "age" );
      long node2 = inserter.createNode( properties );

      inserter.createRelationship( node1, node2, DynamicRelationshipType.withName( "KNOWS" ), null );
      inserter.shutdown();
     }

I would like to store graph data in the database,

     graph.makeEdge( "s", "c", "cost", (double) 7 );
            graph.makeEdge( "c", "e", "cost", (double) 7 );
            graph.makeEdge( "s", "a", "cost", (double) 2 );
            graph.makeEdge( "a", "b", "cost", (double) 7 );
            graph.makeEdge( "b", "e", "cost", (double) 2 );
            Dijkstra<Double> dijkstra = getDijkstra( graph, 0.0, "s", "e" );

What is the best method to store this kind data with 10000's of edges. Then run the Dijskra algorighm to find shortest path calculations using the stored graph data.
