Abstract

There's been substantial interest in recent years in exploring data storage technology that defies the relational model orthodoxy. Many so-called NoSQL databases have grown in this space, each of which tackles problems as diverse as scalability, availability, fault tolerance, and semantic richness. In this talk, I'll provide a brief background on the NoSQL landscape, and a deeper introduction to my latest project Neo4j. Neo4j is a completely open source graph database which efficiently persists data in nodes and relationships and is optimised for extremely fast traversals, providing superior insight into data than is easily possible in traditional relational databases (or the semantically poorer category of NoSQL databases).

Currently Neo4j supports databases bounded by the resources of a single machine (replicated for availability and scale), but we know our research challenges lie ahead. We are away of a reasonable body of literature on graph algorithms to support sharing across physical hosts, but these algorithms tend to make assumptions that may not be valid from the perspective of a dynamically evolving graph, and may even insist on domain-specific knowledge to be potent. In a twist to the usual format where results are presented, this seminar will invite insight and research direction from the audience. At the end of the session, we will have traded a solid grounding in an important emerging technology in the industrial space for the leading edge ideas. Bring your thinking caps!
