Sweden has many IT solutions to be proud of. I assume you are using/have used Spotify or Skype.
Perhaps you are not aware but another “Swedish” product you might have been using is Neo4j, a graph database management system. Graphs are all around us. Typical use cases are recommendation systems, fraud detection and social networks.
I chose to walk the easiest path to learn about Graph data modelling and that was to learn the probably most documented, described, leading Graph Db: Neo4j. After a while I felt comfortable with all the terminology, concepts and programmatic use so I felt confident to take the test to become a Neo4j Certified Professional.
And voila!, here is the result:
The test was harder than expected, the time pressure was significant and some subjects out of scope of my experience (administrator experience in a Production environment) but with logic and wishful thinking I came to a positive result 🙂
So far I have not read too many use-cases where IBM Notes data was used within Neo4j or applications written in XPages using the graph db of Neo4j. But what is not is yet to come…
