Neo4j - Setting up an instance

In this post: 

In this post I am going to show you how to set up and start an external neo4j database instance.

This will be used extensively in later posts. 

Neo4j - Storing data in an embedded database

In this post..  

I hope to describe how to store data in a neo4j embedded database. 

• Create a project which is downloadable by you.
• Create a pom for future apps using neo4j

Possible uses:

• Neo4j projects 
• Small scale applications 
• Proof of concepts

Neo4j Introduction

In this post..  

I hope to set down some details reagarding Neo4J, this is hopefully the first in a collection of posts regarding this tool

An introductory article to Neo4j

Neo4j is an open source NoSQL graph database. It can be up to 100 000 times faster than a relational database in certain circumstances. 

The theory

The theory is that you have a bunch of nodes, and then you create links between each node (Relationships) and on these relationships you can store properties and values (Key-value pairs).

A use case for this could be that you have four bus stops as shown below. A, B, C and D. What you want to find out is the cheapest way to get from A to D. 

Writing new lines to file (OSB)

In this post..  

I hope to describe how to insert a new line into an output used by osb, Reporting, Alerts, Log's 

Possible uses:

• When writing out to a file, you may wish to insert new lines.
• When alerting, reporting, logging, you may wish to insert new lines into all three outputs. 

Setting up a Message Digest (OSB)

In this post..  

I hope to describe how to add a Message Digest to a Business service callout to another Web Service 

Possible uses:

• Mainly security purposes

Making XQuery inputs optional (OSB)

In this post..  

I hope to describe how to make input items on an XQuery mapping callout optional, and possible ways of handling the situation.

Possible uses:

• You are creating an output XML document with an optional field, and are passing this is passed in as a variable on OSB.
  
  

Adding/Receiving custom JMS Headers/Properties (OSB)

OSB Project download - https://sites.google.com/site/jazipfilestorage/files/JMSHeader.zip?attredirects=0&d=1

In this post..  

I hope to describe how to attach non standard JMS headers/properties onto a queue, and then read these off at the next flow. This post assumes the following prior knowledge: 

• How to create Business service's that write to JMS Queue's
• How to create Proxy service's that read from a JMS Queue
• A JMS Queue set up on your server -> Mine is called 'example' 

Possible uses:

• Passing additional information between flows 
• Storing properties which can be used for message selectors
