NEO4J Introduction
Neo4j是一个高性能的,NOSQL图形数据库,它将结构化数据存储在网络上而不是表中。它是一个嵌入式的、基于磁盘的、具备完全的事务特性的Java持久化引擎,但是它将结构化数据存储在网络(从数学角度叫做图)上而不是表中。Neo4j也可以被看作是一个高性能的图引擎,该引擎具有成熟数据库的所有特性。程序员工作在一个面向对象的、灵活的网络结构下而不是严格、静态的表中——但是他们可以享受到具备完全的事务特性、企业级的数据库的所有好处。

NEO4J uses graph-related concepts to describe data models, saving data as nodes in diagrams and relationships between nodes. The relationship between data in many applications can be modeled directly using the concept of nodes and relationships in the diagra
neo4j Introduction Graph database Requirements can be clearly intuitive way to store the graph data, rather than distort the change for other alternative way can simply map operations, such as search, traversal, etc.
The basic idea of the graph database (graph) is composed of nodes (node, vertex) and relation (relationship, edge) to record data on nodes (properties of nodes, property) nodes are organized into graphs by the relationship, and the

understand the relationship is the key to correct use of the graphical database.Note: The node set here is my own translation. In the NEO4J official document, it is called a label. The original is: A label was a named graph construct that was used to group nodes into sets; All nodes labeled with the same label belongs to the same set. I personally feel that the blunt name label is easy to confuse others, so chose the "group nodes into sets" of the fr
