Recently, I've been checking out some NoSQL databases and in particular,
Neo4j has impressed me. I've been looking for ways to leverage our
production data (in Db2) using a graph database (in this case Neo4j).
Importantly though, before I can leverage the data in a new database, I
have to get the data there first. Neo4j offers a few tools for this
purpose on Github - they are essentially ETL tools, one of which is a GUI
and the other is a CLI. The big advantage with the GUI is that, after it
maps out relationships between tables (using primary/foreign keys in a
particular schema/library on source machine), you get a visual
representation of the result and can change it to your liking before
actually loading the data into the Neo4j database (this of course, is
preferable to futzing around with JSON or CSV files directly).

Unfortunately, I've run into a few issues with the GUI tool and have
submitted an issue related to it on Github. Have any of you pulled info
directly from Db2 and loaded it into a NoSQL database like Neo4j or
MongoDB? If so, any thoughts, tips, or war stories would be appreciated!
