    Most probably you are trying to store a graph on your database.

    There are graph databases especially created for storing nodes and connecting nodes with vertices (in your terms, values). http://en.wikipedia.org/wiki/Graph_database#Graph_database_projects

    I’m afraid, there are no free options offered in the cloud for free. You should buy a VPS, Amazon EC2 instance, Windows Azure instance or whatsoever to host your database. Nothing comes free these days.

    Among the graph databases, my choice would be neo4j, it has a good support, documentation, community and it is especially designed for usage with Java (and Scala, of course). However I heard that orientdb and vertexdb are also good for that.
