Peter Neubauer:

- What's the excitement around Neo4J all about?

Lets have some fun and look at some very cool Neo4J demos, covering Neo4J, Heroku, Cypher and how they make difficult stuff fun and easy?

Sebastian Verheughe & Katrina Sponheim:

- .Fun, values and lessons learnt from retrofitting Neo4J into the Telenor middle-ware

Telenor calculated in 2010 that it´s self-service web solution for companies & enterprises, MinBedrift, would not scale with the projected customer growth beyond 2012. In order to achieve acceptable user response times, the current solution was dependent of nightly pre-caching the customers’ data. However, the time available for caching was closing fast, and then response times would become increasingly longer. In the end Telenor would start losing customers, and a lot of money. This is the story about how usage of NoSQL solutions such as Lucene/Solr index & Neo4j graph database solved the problem, and then some more.



Peter has been a founding member of OPS4J and, together with Niclas Hedhman, been involved in the initial discussion of the OPS (Open Participation Software) community model that is practiced here at OPS4J.

Peter has even been a founding member of the Digital Meta Product Library (DPML), where he even heavily contributed.

Born in Eastern Germany, moved to Sweden 1998. Right now, Peter is focusing on turning Open Source Projects into profitable companies. Also, Peter is helping technology and mobile startups and organizing events like ThoughtMade and TEDx Öresund.

Peter is Interested in creating products with a sustainable community process and Open Participation especially. Trying to formulate the arguments of why industrial companies (i.e. non-IT companies) should invest money into OSS projects by actively participating, instead of paying consultants inhouse, and in the process create a better value proposition for their and ensure sustainable development and support for the externally managed OSS parts.

Sebastian Verheughe, System Architect, Telenor Norway Currently working at Telenor Norway as a system area architect, Sebastian is responsible for business services in the mobile value chain. The last year he has been working on a project looking into how such services better can support search and retrieval of large dynamic data sets by the clients.

Katrina Sponheim, System Architect, Telenor Norway Katrina is the system architect of Telenor Norway’s self service web solutions for the business segment. She has during the last year been involved in scalability and performance improvements related to customers being exposed to large data sets.

    Working on it, I just have to make some minor modifications to it before I am allowed to publish it outside Telenor. Give me a couple of days...

    Were the slides from Sebastian and Katrina ever made available anywhere?

    Exciting shiznit. Could perhaps have a short demo of how to convert a regular SQLDB to Neo. How to think, what to expect of performance + complexity gains

    Impressive performance in graph traversal. Looks like a technology that suits a lot of problem domains where one often would use a lot of awkward-forever-nesting-joins.

    Highly interesting topic with some really cool examples. Solid presentations from all, but it was sometimes difficult to hear the last presenter.
