Introduction to NoSQL and MongoDB along with step by step walkthrough on how to integrate MongoDB with the Spring MVC framework. Full source code available for example project from http://automateddeveloper.blogspot.com

1. Hands-on NoSQL MongoDB & Spring Integration http://automateddeveloper.blogspot.com

3. Neither I, nor this presentation, are in any way affiliated with SpringSource or MongoDB

7. Many leading web 2.0 sites now use NoSQL implementations:Facebook – Cassandra (originally developed in-house and later open-sourced Twitter – Hadoop & Cassandra Google – BigTable Digg – Cassandra FourSquare - MongoDB

8. In the News 4,850% Percent increase in NoSQL jobs since November 2009 as reported by SimplyHired.com $14million Amount raised in Series C Funding last week by CouchBase for further investment in to NoSQL solutions(Aug2011) 8TB Amount of data generated everyday in Twitter, and needs to be supported by their NoSQL solution (figure from 2010)

10. Dynamic schemas, storing data in JSON style documents that allows for addition of data on the fly

11. Supports indexing of documents

15. Only the configuration to connect an existing Spring MVC app will be covered in detail

16. Before proceeding, install MongoDB – full details are available: http://www.mongodb.org/display/DOCS/Quickstart

19. @Id on any member variable to be used as an identifier for the object (must be String/int/long)

21. In our Resume example, only our top level “Resume” object needs to be annotated and we will only be persisting/retrieving at this level (Document based DB makes sense for this model, as a “ResumePage” only makes sense within the context of a “Resume” and not as an object in itself)

22. Using JPA, all three objects would be annotated “@Entity” and all could be queried as independent objects@Document public class Resume@Idprivate String id; public class ResumePage public class PageSection

26. There is no real change in the Service or Controller Layers to the normal Spring MVC approach

32. NoSQL should be considered as another tool in the arsenal – RDBMS is not going anywhere!
