6. AGENDA Review of Relational Databases Gr8Ladies Example Application NoSQL Definition Types of NoSQL data stores Example MongoDB Redis
7. WHAT WILL NOT BE COVERED Every aspect of every NoSQL solution Implementation, maintenance, or scaling of NoSql databases
8. RELATIONAL DATABASES Tabular Defined Schema Relationships between data Terms Database Table Row Column
9. REVIEW
10. GROOVY Dynamic, compiled language for the Java Virtual Machine(JVM). Interoperable with existing Java libraries Concise, easy to read code Used by many major companies including:
11. GRAILS Groovy Based Model View Controller(MVC) Web framework for the JVM Convention over Configuration Features including: Object Relational Mapper(ORM) Domain-Specific Languages(DSL) Runtime and compile-time Metaprogramming Extensive Plugin Support Open-source community driven Project
12. NEW IN GRAILS 3 Based on Spring Boot Switched to Gradle for build system Major structural changes Configuration Scripts
13. EXAMPLE TASK Gr8Ladies Products Catalog Products Shopping Cart
14. WHAT IS NOSQL? Not Only SQL Group of data storage solutions that are not Relational Database Management System(RDBMS) Schema-less Non-relational
15. GOALS OF NOSQL Volume Velocity
16. TYPES OF NOSQL SOLUTIONS Aggregate Stores Key-value Document Column Graph
17. KEY-VALUE STORES
18. USES Content Caching Transient Data Session Data Image Stores
19. EXAMPLES MemCached DynamoDB Redis*
20. CONSIDERATIONS Relationships Transactions Querying
21. LIBRARIES & PLUGINS Status Last Updated June 2014 Last Updated December 2011 Last Updated April 2012 Jedis Grails Redis Redis GORM Memcached 2nd-Level Cache Plugin DynamoDB GORM
22. DOCUMENT STORES
23. USES Content Management Systems(CMS) / Blogging Platforms Forms/data with many optional fields Frequently Changing Schemas
24. EXAMPLES CouchDB RavenDB Azure DocumentDB MongoDB
25. CONSIDERATIONS Complex transactions across documents Complex searching
26. LIBRARIES & PLUGINS Status Last Updated March 2015 Last Updated April 2011 GMongo MongoDB GORM CouchDB GORM
27. COLUMN FAMILY
28. USE CASES CMS Systems/ Blogging Platforms Log Aggregators Incremental Counters
29. EXAMPLES Cassandra HBase Hypertable
30. CONSIDERATIONS Schema Changes Arbitrary unstructured data
31. TO LEARN MORE Grails and Cassandra http://greachconf.com/speakers/jeff-beck-grails-and-cassandra/
32. GRAPH DATABASES
33. TYPES Labeled Property Graph Hypergraphs Triples
34. USES Social Networks E-commerce Recommendations Geo Nearby Locations and Routing
35. EXAMPLES Neo4J OrientDB Allegro Graph
36. CONSIDERATIONS Deep tree traversals* Very different way of thinking about data
37. LIBRARIES & PLUGINS Status Native REST API Last Updated June 2014 Neo4j GORM

39. HOW DO I PICK JUST ONE? YOU DON'T HAVE TO!
40. APPROACH # 1 All In - M o n g o D B G O R M
41. MONGODB Terminology Databases Collections Document
42. MONGODB CONTINUED Highlights Created When Needed Databases Collections Optional Fields BSON Object Ids over Integers
43. APPROACH # 2 Partial - G r a i l s - R e d i s p l u g i n
44. REDIS Terminology Keys Types String Hash Sets
45. HIGHLIGHTS Organized/Indexed Keys CRUD operations Key Expiration Service Level Injection rather than all of GORM
46. CONCLUSION Picking a NoSQL solution depends on the problem Not every tool is the right one for the job NoSQL stores are valid alternatives to relational databases NoSQL solutions are highly supported in Groovy and Grails
