Neo4j官方示例练习、学习

写在前面

主要包括以下几个个方面的学习，基于 docker服务部署

Docker 部署如下命令

1. 下载镜像：docker pull neo4j:3.5.0
2. 运行容器：docker run -d -p 7474:7474 -p 7687:7687 --name neo4j-3.5.0 neo4j:3.5.0
3. 停止容器：docker stop neo4j-3.5.0
4. 启动容器：docker start neo4j-3.5.0
5. 浏览器 http://192.168.1.74:7474/ 访问 neo4j 管理后台，初始账号/密码 neo4j/neo4j

两个基本问题

• 怎么用？
• 什么时候用？

一、基本介绍

Neo4j、TigerGraph、Amazon Neptune、JanusGraph、ArangoDB，是市场上最为知名的五大图数据库。

Neo4j是世界领先的图形数据库。 它的体系结构旨在优化管理，存储和遍历节点和关系。 该数据库采用一种属性图方法，这对于遍历性能和操作运行时都非常有利。 Neo4j提供专用的内存管理以及高效的内存操作。

它具有可伸缩性，可以部署为独立服务器，也可以在容错群集中的多台计算机上横向扩展以用于生产环境。 生产应用程序的其他功能包括热备份和广泛的监视。

目前只提供了 官方的驱动和 Java 客户端

服务端版本 包括社区版和商业版

二、Get start

几个概念
Nodes - graph data records
Relationships - connect nodes
Properties - named data values
Label - Nodes can be grouped together by applying a Label to each member

2.1、Cypher 基础

相当于sql 管理数据库

create

CREATE (ee:Person {
    name: "Emil", from: "Sweden", klout: 99 })

注释
CREATE clause to create data
() parenthesis to indicate a node
ee:Person a variable 'ee' and label 'Person' for the new node
{
   } brackets to add properties to the node

MATCH

MATCH (ee:Person) WHERE ee.name = "Emil" RETURN ee;

注释
MATCH clause to specify a pattern of nodes and relationships
(ee:Person) a single node pattern with label 'Person' which will assign matches to the variable 'ee'
WHERE clause to constrain the results
ee.name = "Emil" compares name property to the value "Emil"
RETURN clause used to request particular results

关系

MATCH (ee:Person) WHERE ee.name = "Emil"
CREATE (js:Person {
    name: "Johan", from: "Sweden", learn: "surfing" }),
(ir:Person {
    name: "Ian", from: "England", title: "author" }),
(rvb:Person {
    name: "Rik", from: "Belgium", pet: "Orval" }),
(ally:Person {
    name: "Allison", from: "California", hobby: "surfing" }),
(ee)-[:KNOWS {
   since: 2001}]->(js),(ee)-[:KNOWS {
   rating: 5}]->(ir),
(js)-[:KNOWS]->(ir),(js)-[:KNOWS]->(rvb),
(ir)-[:KNOWS]->(js),(ir)-[:KNOWS]->(ally),
(rvb)-[:KNOWS]->(ally)

MATCH (ee:Person)-[:KNOWS]-(friends)
WHERE ee.name = "Emil" RETURN ee, friends

注释
MATCHclause to describe the pattern from known Nodes to found Nodes
(ee)starts the pattern with a Person (qualified by WHERE)
-[:KNOWS]-matches "KNOWS" relationships (in either direction)
(friends)will be bound to Emil's friends

explain/PROFILE 执行计划

PROFILE MATCH (js:Person)-[:KNOWS]-()-[:KNOWS]-(surfer)
WHERE js.name = "Johan" AND surfer.hobby = "surfing"
RETURN DISTINCT surfer

3.2、Find

• 1、Find the actor named “Tom Hanks”…

MATCH (tom {
   name: "Tom Hanks"}) RETURN tom

• 3、Find the movie with title “Cloud Atlas”…

MATCH (cloudAtlas {
   title: "Cloud Atlas"}) RETURN cloudAtlas

• 4、Find 10 people…

MATCH (people:Person) RETURN people.name LIMIT 10

• 5、Find movies released in the 1990s…

MATCH (nineties:Movie) WHERE nineties.released >= 1990 AND nineties.released < 2000 RETURN nineties.title

3.3、query

• List all Tom Hanks movies…

MATCH (tom:Person {
   name: "Tom Hanks"})-[:ACTED_IN]->(tomHanksMovies) RETURN tom,tomHanksMovies

• Who directed “Cloud Atlas”?

MATCH (cloudAtlas {
   title: "Cloud Atlas"})<-[:DIRECTED]-(directors) RETURN directors.name

• Tom Hanks’ co-actors…

MATCH (tom:Person {

3.4、Solve

• Movies and actors up to 4 “hops” away from Kevin Bacon

MATCH (bacon:Person {
   name:"Kevin Bacon"})-[*1..4]-(hollywood)
 RETURN DISTINCT hollywood

• Bacon path, the shortest path of any relationships to Meg Ryan

MATCH p=shortestPath(
  (bacon:Person {
   name:"Kevin Bacon"})-[*]-(meg:Person {
   name:"Meg Ryan"})
)
RETURN p

Note you only need to compare property values like this when first creating relationships

3.5、delete

MATCH (n) DETACH DELETE n

3.6、load 加载CSV数据

LOAD CSV WITH HEADERS FROM "http://data.neo4j.com/northwind/products.csv" AS row
CREATE (n:Product)
SET n = row,
  n.unitPrice = toFloat(row.unitPrice),
  n.unitsInStock = toInteger(row.unitsInStock), n.unitsOnOrder = toInteger(row.unitsOnOrder),
