The aha!s and the oh-noe!s of over one year of building our product with a graph database, Neo4j, along with big brother PostgreSQL and hipster cousin Redis with Rails.
This talk will attempt to answer an important question, "when does using a graph database make sense?", through retrospection.
Performance of graph query languages:
Analysis on theperformance of graph querylanguages: comparative study of Cypher, Gremlin and native access in Neo4j
Relational databases were conceived to digitize paper forms and automate well-structured business processes, and still have their uses. But RDBMS cannot model or store data and its relationships without complexity, which means performance degrades with the increasing number and levels of data relationships and data size. Additionally, new types of data and data relationships require schema redesign that increases time to market.
A native graph database like Neo4j naturally stores, manages, analyzes, and uses data within the context of connections meaning Neo4j provides faster query performance and vastly improved flexibility in handling complex hierarchies than SQL.

There are many ways to use Neo4j from Java. In this talk I want to demonstrate different APIs and examples on how to build solutions on top of Neo4j using a Java based stack.
Getting started with Graph Databases & Neo4jSuroor Wijdan
The presentation gives a brief information about Graph Databases and its usage in today's scenario. Moving on the presentation talks about the popular Graph DB Neo4j and its Cypher Query Language i.e., used to query the graph.
The trend nowadays is to represent the relationships between entities in a graph structure. Neo4j is a NOSQL graph database, which allows for fast and effective queries on connected data. Implementation of own algorithms is possible, which can improve the functionality of built in API. We make use of the graph database to model and recommend movies and other media content.
This tutorial will provide you with a basic understanding of graph database technology and the ability to quickly begin development of a graph database application. You will have the capability to recognize graph-based problems and present the benefits of using graph technology for problem resolution.
The tutorial will give you an understanding of:
• Graph theory - origins and concepts
• Benefits of graph databases
• Different types of graph databases
• Typical graph database API
• Programming basics
• Use cases
Bring your laptops for a hands-on opportunity to practice some sample codes. A basic understanding of Java programming is a recommended prerequisite to understand this course. This session is led by the InfiniteGraph technical team and the demonstration code will be drawn from InfiniteGraph examples, however the broader educational presentation is product-neutral and not a commercial presentation of their products.
To participate in the hands-on portion of the graph tutorial users must have:
• Java programming experience
• Java Developer Kit (JDK)
• Current InfiniteGraph installed on laptop. (To download visit www.objectivity.com/infinitegraph)
• HelloGraph test – Upon installing IG, run HelloGraph to test the install. (HelloGraph can be found online at http://wiki.infinitegraph.com/2.1/w/index.php?title=Download_Sample_Code)

The openCypher Project - An Open Graph Query LanguageNeo4j
We want to present the openCypher project, whose purpose is to make Cypher available to everyone – every data store, every tooling provider, every application developer. openCypher is a continual work in progress. Over the next few months, we will move more and more of the language artifacts over to GitHub to make it available for everyone.
openCypher is an open source project that delivers four key artifacts released under a permissive license: (i) the Cypher reference documentation, (ii) a Technology compatibility kit (TCK), (iii) Reference implementation (a fully functional implementation of key parts of the stack needed to support Cypher inside a data platform or tool) and (iv) the Cypher language specification.
We are also seeking to make the process of specifying and evolving the Cypher query language as open as possible, and are actively seeking comments and suggestions on how to improve the Cypher query language.
The purpose of this talk is to provide more details regarding the above-mentioned aspects.

Big Data Analytics 2: Leveraging Customer Behavior to Enhance Relevancy in Pe...MongoDB
This session covers how to capture and analyize customer behavior to create more relevent contexts for customers. We will cover how to use your current BI features, and more importantly, how newer technologies approach the challenge. You will walk away with a good idea on how to build and drive even more contextually relevant experiences to customers for even more successful engagements.
Introduction to Graph database, using K-pop as a database modelling case. From the idea of graph database, Neo4j installation, modelling, Cypher to business application.
One of the challenges that comes with moving to MongoDB is figuring how to best model your data. While most developers have internalized the rules of thumb for designing schemas for relational databases, these rules don't always apply to MongoDB. The simple fact that documents can represent rich, schema-free data structures means that we have a lot of viable alternatives to the standard, normalized, relational model. Not only that, MongoDB has several unique features, such as atomic updates and indexed array keys, that greatly influence the kinds of schemas that make sense.

If we’re producing analysis that drives business decision making, that’s production-grade code! This talk will address this question, which in turn shows why R is the way to go – assumptions are built into the code and enables the analyst to automate & reproduce their efforts.
This presentation includes:
- Data importing (opening a CSV or connecting to a SQL in both tools)
- Filtering, grouping, summarizing (pivot tables in Excel vs. tidy code in R)
- Visualizations (charts in excel vs ggplot in R)

Why Hacking WordPress Search Isn't Some Big Scary ThingChris Reynolds
Developers can be a stubborn lot. We like to focus on the things we know really well, and things we don’t deal with as often can be seen as “hard”. Search is one of those things that gets written off a lot, few devs I know will deal with it (voluntarily), and almost everyone will tell you “WordPress search sucks.” In this presentation you will learn that not only do you know more about how search works than you thought you did, but maybe give you a better understanding of how WordPress works as a whole, as well as showing you some cool tricks that you can do with WordPress search.
Workbook: http://ibm.biz/devoxxfr_workbook
When it’s time to choose the database technology for your app, the choices can be overwhelming. Should you choose SQL or NoSQL? Open source or proprietary? Self-hosted or hosted? If you’re not already familiar with graph databases, you might be tempted to ignore them as an option. But that could be a mistake.
In this hands-on lab, we'll discuss the benefits of graph databases and the basics of how to use one. Then we'll open our laptops and begin coding! We'll explore an existing app that leverages a hosted version of the open-source graph computing framework Apache TinkerPop. We'll discover how we can use APIs and the Gremlin graph traversal language to perform CRUD (create, read, update, and delete) operations. Then we'll write our own code to perform a CRUD operation and explore the graph. Most exciting of all, we'll write code to generate recommendations (one of the biggest strengths of graph databases!) for the app's users.
So bring your laptop with a modern web browser installed, and get ready to graph! You'll leave with an understanding of when you should choose a graph database and how to use one.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
