Martin Fowler

I am an author, speaker, and loud-mouth on the design of enterprise software.
I work forThoughtWorks, a software delivery and consulting company. This site
contains lots of my writing on software development, which primarily focuses
on software design and agile methods.

Not using the relational model (nor the SQL language)
Open source
Designed to run on large clusters
Based on the needs of 21st century web properties
No schema, allowing ﬁelds to be added to any record without controls

Document-Oriented Database

1.)


A document-oriented database is a computer program designed for storing,
retrieving, and managing document-oriented information, also known as semistructured data. Document-oriented databases are one of the main categories
of so-called NoSQL databases and the popularity of the term "documentoriented database" (or "document store") has grown[citation needed] with the
use of the term NoSQLitself. In contrast to well-known relational databases
and their notions of "Relations" (or "Tables"), these systems are designed
around an abstract notion of a "Document".

Column Oriented Database

A column-oriented DBMS is a database management system (DBMS) that
stores data tables as sections of columns of data rather than as rows of data. In
comparison, most relational DBMSs store data in rows. This[ambiguous] has
advantages for data warehouses, customer relationship management (CRM)
systems, and library card catalogs, and other ad hoc inquiry systems[1] where
aggregates are computed over large numbers of similar data items.

3.

Key Value Stores

They all allow storage of arbitrary data which is being indexed using a single key to allow retrieval.
Key value stores allow the application developer to store schema-less data. This
data is usually consisting of a string which represents the key and the actual
data which is considered to be the value in the "key - value" relationship.
They all allow storage of arbitrary data which is being indexed using a single key
to allow retrieval.

A little talk about
graph databases and
Neo4j

http://somefun.net/fun/wp-content/uploads/2013/01/The-only-way-to-see-grumpy-cat-happy.jpg


Agenda:
Introduction
The fairytale about Neo4j
- Johnny Depp, Cats, Earth, Napster, Friends, Customer, Application map
Graphs are everywhere
- social, linked, interest graph
Graph Databases
- What is it? My little pony s, Matrix, Tom Hanks, Patterns, Movies, Query
language

DEMO
Become a graphista?
Thank you!

Let’s build
a graph database!



And called it Neo,
since we all
love The Matrix



And make it
open-source
so everyone
can join the fun

CYPHER

Cypher is Neo4j's graph query language


// get node with id 0
start n=node(0) return a
// find nodes connected to node 1
start n=node(1) match (n)-->(m) return m
// create a node
create (me {name:'Pernilla'})
// delete relationship
start n=node(1) match (n)-[r]->(m) delete r
