SO WHAT CAN IT DO? Whiteboard Friendly Focuses on Relationships Can store billions of nodes Another Boring Generic Explanation ZZZZZZZZZZZZZZZZ Tuesday, 4 June 13
WHAT YOU TALKIN... I’m a software engineer I’m not smart This talk is not in-depth If I can understand it you can! This talk might be wrong! ;) I show/teach by ‘doing’ Tuesday, 4 June 13
WHAT IS A GRAPH DB? Composed of nodes (verticies) & relationships (edges) Completely different paradigm from SQL As stated previously it focuses on the relationship between values and the commonalities among a ‘set’ of values Tuesday, 4 June 13
NODES A node is a “vertex between edges that may hold data”. I call it “a wee box of data stores”. [name: Homer] [name: Lenny] [name: Carl] Tuesday, 4 June 13
CYPHER Cypher is a graph query language supported by Neo4j. Based on pattern matching and a SQL-like syntax. ..... and I didn’t use it - much. Tuesday, 4 June 13
GROOVY - GREMLIN I know this is a Ruby talk but I did this on my spare time and I wanted to “mess about” As much as I hate to admit it - I am becoming a fan of the ‘jvm’. I feel it gives you a more intimate/natural access. Deal with it ;) Tuesday, 4 June 13
GROOVY - GREMLIN Gremlin is a DSL for Groovy. It is a handy (for me anyway) way to get to grips with graph databases. Your mileage may vary. Tuesday, 4 June 13
GREMLIN CONSOLE As you can see... It uses proper math terms. Which is no good to a thick fuck like me. It also isn’t the fastest on my mac however I wanted to learn. Tuesday, 4 June 13
RUSSELL “STRINGER” BELL name: 'Russell Bell', alias: 'Stringer', first_appearance: '1.01', last_appearance: '3.12', section: 'The Street' Tuesday, 4 June 13
WHAT I WANTED TO DO Show the relationships between the characters on a personal and professional level. Create a database that showed (given one episode) who talked to who and in how it added to the story. Show that Clay Davies is in “everyones shit”. Tuesday, 4 June 13
WHAT I WILL DO On my spare time and reporting back on my blog (http://blog.swm.cc) - I will continue on with this. Would be great to have an engine that allowed us to detail every scene of the “street involving Bodie and see who he has interacted with” Tuesday, 4 June 13
END GAME Neo4j is a very interesting bit of kit. It can be used for more than building. recommendation lists. Very powerful for ‘Big Data’. Distributed High Availability. Tuesday, 4 June 13
NEO4J STRENGTHS Graph databases are great for unstructured data. Was hoping to go back and show adding in ‘rank’ to ‘the street’ and ‘the law’ nodes but leaving it out of the rest. No constraints on data - it really is a ‘free for all’. Tuesday, 4 June 13
NEO4J STRENGTHS According to the documentation it can handle 34.4 billion nodes and 34.4 billion relationshops. Integrates with Lucene and has many extensions. Tuesday, 4 June 13
NEO4J WEAKNESS If you aren’t used to modelling ‘graph data’ like I was you might find it hard to get your head round the concept. To be honest I am not sure if I am there. Tuesday, 4 June 13
WHAT I WOULD LIKE As a community I would like someone here today to take what I have done here and create a ‘ruby’ extension to query the data. Everything will be available on my github account which you can get from my site (http://swm.cc) Tuesday, 4 June 13
