GraphTalks Rome - Selecting the right Technology

  1. 1. Selecting the right technology and best practices with a focus on Graphdatabases Dirk Möller
  2. 2. About me • 20 years in software sales • 8 years OSS • 2012/13 Neo Technology • 2014 MongoDB • 2015/16 Couchbase • Oct 2016 Neo
  3. 3. The interne
  4. 4. DB landscape
  5. 5. Total DB market trend
  6. 6. OSS threatens to eat the DB market
  7. 7. What is NoSQL? A NoSQL (originally referring to "non SQL", "non relational" or "not only SQL")[1] database provides a mechanism for storage and retrieval of data which is modeled in means other than the tabular relations used in relational databases. Wikipedia
  8. 8. What is NoSQL? KV Store Key-value (KV) stores use the associative array (also known as a map or dictionary) as their fundamental data model. In this model, data is represented as a collection of key-value pairs, such that each possible key appears at most once in the collection Document Store A document-oriented database, or document store, is a computer program designed for storing, retrieving, and managing document- oriented information, also known as semi-structured data. ... XML databases are a subclass of document- oriented databases that are optimized to work with XML documents
  9. 9. Database Rel and NoSQL • Rel RDBMS • Tabular, structured data • Highly transactional • Processing of simple lists • Fixed schema • Already in house (most of time) • KV • Login use cases • High write throughput • Easy schema • Document • Unstructured data • Lots of shattered data • Storing of such data • Graph – more a category of it’s own • Highly connected data • Very dynamic data such as hierarchies and networks • Transactional • Structured data • Knowledge vs pure storing
  10. 10. Graphdatabases
  11. 11. Neo4j Competitive Posture 6x More Popular than Runner Up Our leadership position is strong: • Native Graph • Most mature • Most customer successes • Technical strengths (perf & trust) • Largest community • Graph leadership (e.g. openCypher) • Most contributors • Strong financial backing 18 Source: DB-Engines Popularity Index, January 2016
  12. 12. Industry’s Largest Dedicated Investment in Graphs Features (20%) Neo4j Infrastructure (80%) “The Other Guys” Small handful of engineers working on graphs Compared to Neo4j, compromises: 1) Reliability 2) Depth of graph features • 130+ employees • $80M+ funding • 40+ Full-Time Product Engineers (growing to 60+ in 2017) • Nearly a decade of product maturity & use 100% dedicated to graphs
  13. 13. * Monash Research http://www.dbms2.com/2013/03/18/dbms-development-marklogic-hadoop/ Time to Build Graph API Fast Performance Connected Queries in Real Time Reliability Data Trustworthiness Native Graph Full Stack 5 to 7+ years* ✔ ✔ ✔ Graph on RDBMS 3 to 5 years ✔ Underlying DBMS 1000 times slower for key operations ✔ Graph on other NOSQL 3 to 5 years ✔ Underlying DBMS lacks semantic and architecture for connecting data “Eventually consistent" leads to "eventually corrupt" A Native Graph Database is Uniquely Valuable …and Not Easily Replicable The Cardinal Rules of DBMS Development*:
  14. 14. Why Graphdatabases
  15. 15. Traditional Approach: Tables
  16. 16. The Whiteboard Model Is the Physical Model
  17. 17. A Naturally Adaptive Model Flexibility
  18. 18. Graph Based Success
  19. 19. Discrete Data Minimally connected data Neo4j is designed for data relationships Other NoSQL Relational DBMS Neo4j Graph DB Connected Data Focused on Data Relationships Development Benefits Easy model maintenance Easy query Deployment Benefits Ultra high performance Minimal resource usage Use the Right Database for the Right Job
  20. 20. Relational DBs Can’t Handle Relationships Well • Cannot model or store data and relationships without complexity • Performance degrades with number and levels of relationships, and database size • Query complexity grows with need for JOINs • Adding new types of data and relationships requires schema redesign, increasing time to market … making traditional databases inappropriate when data relationships are valuable in real-time Slow development Poor performance Low scalability Hard to maintain
  21. 21. Relational Versus Graph Models Relational Model Graph Model KNOWS ANDREAS TOBIAS MICA DELIA Person FriendPerson-Friend ANDREAS DELIA TOBIAS MICA
  22. 22. NoSQL Databases Don’t Handle Relationships • No data structures to model or store relationships • No query constructs to support data relationships • Relating data requires “JOIN logic” in the application • No ACID support for transactions … making NoSQL databases inappropriate when data relationships are valuable in real-time
  23. 23. Unlocking Value from Your Data Relationships • Model your data as a graph of data and relationships • Use relationship information in real- time to transform your business • Add new relationships on the fly to adapt to your changing business
  24. 24. The Whiteboard Model Is the Physical Model
  25. 25. Neo4j – Re-Imagine Your Data as a Graph Neo4j is an enterprise-grade graph database that enables you to: • Model and store your data as a graph • Query data relationships with ease and in real-time • Seamlessly evolve applications to support new requirements by adding new kinds of data and relationships Agile development High performance Vertical and horizontal scale Seamless evolution
  26. 26. Real-World Neo4j Business Benefits New Competitiveness • New, unique functionality • New insights into data Better Software • Better code quality • Less complexity • More maintainable Using the right tool for the job has profound effects on your business User Success • Faster app performance • Better user experience • Improved user productivity Project Success • Faster time to market • Lower costs Neo4j creates a connected data imperative
  27. 27. Value from Data Relationships Common Use Cases Internal Applications Master Data Management Network and IT Operations Fraud Detection Customer-Facing Applications Real-Time Recommendations Graph-Based Search Identity and Access Management
  28. 28. Quick Start: Plan Your Project 1 2 3 4 5 6 7 8 Learn Neo4j Decide on Architecture Import and Model Data Build Application Test Application Deploy your app in as little as 8 weeks PROFESSIONAL SERVICES PLAN
  29. 29. There Are Lots of Ways to Easily Learn Neo4j
  30. 30. • NEO4J • MYTHS AND FACTS  “Neo4j only makes sense for special use cases like social networks”  “Is Neo4j really enterprise ready?”  “Neo4j only has nodes and relationships, is this really sufficient for a complex business application?”  “Users always work with graphs?”  “Is this database fast enough?”
  31. 31. • NEO4J • SIX ARGUMENTS FOR NEO4J  Much easier mapping of business domain model to the graph database  Business understands the graph model  Hierarchical structures easy to query  Less queries, less development, faster and cheaper results  Full scalability (embedded to cluster)  Automated testing, supporting libraries  Integrated Lucene full text search engine  Full text search as part of the Cypher query  Extension architecture  Amazing performant results
  32. 32. Summary Only Neo4j Unlocks the Value in Your Data Relationships Data is increasing in volume… • New digital processes • More online transactions • New social networks • More devices … and is getting more connected Customers, products, processes, devices interact and relate to each other
