# Neo4j-Project
## Professor - Dr IAN McLOUGHLIN
#### The project is made for as a part of college work , Module GRAPH THEORY .
#### Neo4j
Neo4j is the world's leading open source Graph Database which is developed using Java technology. It is highly scalable and schema free (NoSQL).
A graph is a pictorial representation of a set of objects where some pairs of objects are connected by links. It is composed of two elements - nodes (vertices) and relationships (edges).
Graph database is a database used to model the data in the form of graph. In here, the nodes of a graph depict the entities while the relationships depict the association of these nodes.
### Database
To create this Database all the information is retrieved from the Wikipedia , The nature of datbase is each and every node is created sepretly and each and every single node represents either a county or a members , so there is 40 consituencies is in Ireland so there is all together 40 nodes in the database which represents all the consituencies of ireland.
### Querie Shows how to create the node in database which represents a consituency Carlow–Kilkenny.
```
CREATE ( CarlowKilkenny : constituencies {Name : "Carlow–Kilkenny" })
```
### Querie Shows how to create the node in database which represents a each member of Carlow–Kilkenny.
```
CREATE (CarlowKillkenny1 : candidate_CK { Name : "John McGuiness", Gender : "Male" , Age : 40 ,
PartyName : "FiannaFail", TotalVotes : 11903 ,County : "Carlow–Kilkenny" ,Win : "Yes" })
```
### Querie Shows how to create a relationship between the given candidate with the given county .
```
MATCH (u:constituencies {Name:"Carlow–Kilkenny"}), (r:candidate_CK)
CREATE (u)-[:Ran_IN_Election]->(r)
```
Above query shows how to create a relationship between constituency name Carlow–Kilkenny with the all the candidate of that constituency,
firstly we have to match the nodes together in datbase , For eg in the constituencies match a node name called Carlow–Kilkenny and match a another node in that candidate_CK and make a relationship between them and give a relationship name called a Ran_IN_Election.
### Quickstart
First, you need to have a local Neo4j running. The easiest way is Docker. If you have a docker installed locally, than please run .
```
docker run --publish=7474:7474 --publish=7687:7687 -e 'NEO4J_AUTH=neo4j/secret' neo4j:4.1
```
Another option is to use Neo4j desktop, which can be downloaded from here: http://neo4j.com/download. If you chose that way, install and start as instructed by the desktop application. You need to start a new database inside desktop.
1. After you have Neo4j up and running, open up a browser and goto http://localhost:7474. Enter the credentials (neo4j:secret if you chose the Docker approach above or the credentials you supplied in Neo4j Desktop).
2. click and run the Cypher statement to insert the dataset .
3. Clone this project from GitHub.
### Queries Walkthrough
```
MATCH
(n)
RETURN
n;
```
This query Will Shows whats actually exixts in database and how is the structure of database.
In terms of relationship with all of the members of the given county .
### This query will show a user that how many nodes are in the databse It will count a total number of nodes .
```
start n=node(*)
match (n)
return count(n)
```
### This query will Get the number of female members were there in county kerry, who run in election With there names and age .
```
MATCH(a:constituencies{Name : "Kerry"})-[:Ran_IN_Election]->
(b:candidateKerry)
WHERE b.Gender = "Female"
RETURN b.Name , b.Age;
```
### This query retreives a oldest man name and age who run in election in county clare.
```
MATCH(a:constituencies{Name : "Clare"})-[:Ran_IN_Election]->
(b:candidate_Clare)
WHERE b.Age >= 70
RETURN b.Name , b.Age;
```
### This query will Find the list of people who won the election for more than 12000 votes , Their Names , Total Number of votes they got And was male or female and count them how many are their were .
```
MATCH(a:constituencies{Name : "Clare"})-[:Ran_IN_Election]->
(b:candidate_Clare)
WHERE b.TotalVotes >=12000
RETURN b.Name , b.TotalVotes, b.Gender ,b.Age, Count(*);
```
