What is NoSQL?
NoSQL means Not Only SQL
The NoSQL umbrella covers a range ofnon-relational databases, including key-value, document , wide column store
and graph based databases

Why NoSQL?
NoSQLs recent increase in popularitybeing largely driven by the explosionin amount of data that is now being
created/captured on the web
Many leading web 2.0 sites now useNoSQL implementations:
Facebook Cassandra (originallydeveloped in-house and later open-sourced
Twitter Hadoop & Cassandra

MongoDB
An Open Source Documentoriented database
Dynamic schemas, storingdata in JSON style documents thatallows for addition of data on the fly
Supports indexing of documents Auto-sharding supported, providing
full horizontal scaling

MongoDB & Spring
Core Spring and the SpringMVC framework areenterprise standard Java
libraries for buildingprofessional web sites
As more and more web sites need to
be able to handle huge amounts ofdata, there will be an increased needto be able to build professional sites
incorporating NoSQL solutions

Getting Started
This overview does not cover detailsof setting up a Spring MVC app, andwill assume a working knowledge of
the framework
Only the configuration to connect anexisting Spring MVC app will be
covered in detail
Before proceeding, install MongoDB full details are available:

Domain Objects
Similar to using JPA(Hibernate, etc)the first step is to model theunderlying Domain objects you want
to use to model the applicationsunderlying meta-data.
Using Spring Data
we can model ourdomain using POJOsand annotations.

Domain Objects
@Document annotation on the rootDocument object
@Id on any member variable to beused as an identifier for the object(must be String/int/long)
The @Id field must either be namedid, or the annotation used incombination with aMappingConverter

Data Access TheRepository
Core CRUD functionality can beachieved out-of-the-box by extendingthe MongoRepository class
This provides save(), findAll(),findOne() and delete() methods
that can be used on our @Document
object (in our case Resume.java)

Data Access TheRepository
Our Repository interface can easilybe extended to include custommethods, and the MongoTemplate
class provides an API to createcustom queries:
mongoTemplate.find(COLLECTION_NAME, newQuery(Criteria.where(name).is(searchTerm)), Resume.class);
Criteria allows querying by any fieldn m in n m nt

Service Layer
The majority of the MongoDBimplementation is abstracted to theData Access layer through the
MongoRepository There is no real change in the
Service or Controller Layers to the
normal Spring MVC approach In the Service class we can just auto-
wire the Repository Interface in to
the class just like we would normally

A change to your application config isneeded to support access toCloudFoundry MongoDB service
Notice the only change is themongoDbFactory bean is being
instantiated with no constructor

Thoughts
NoSQL is growing in popularity but isnot intended to be a replacement forRDBMS
NoSQL should be considered asanother tool in the arsenal RDBMSis not going anywhere!
Database technology choice shouldbe driven by the requirements of theproblem Document oriented have
specific applications
