From this perspective, a graphical database such as neo4j can be used to better describe the domain model of the application.As with relational databases, when using NEO4J, you can use either Neo4j's own APIs or a third-party framework.

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。

organizing the digitized data of vector structure map in geographic information system.2. neo4j Brief IntroductionNEO4J is now the mainstream of a graph database, compared to the traditional relational database. It can make query and retrieval based on interpersonal social network class at high speed; it provides the cypher language at the same time to facilitate the operation and query of the graph database, which is similar to the SQL language.3.
represents the node's number, R1~R7 represents the relationship number, and P1~P10 represents the property's number.
The storage sample diagram for node is as follows, with each node saving the 1th and 1th relationship:
The storage diagram for the relationship is as follows:
From the schematic, it can be seen from the node-b start, through the relationship of the next pointer, you can traverse the node-b of all the relationships, and then you can reach the 1th layer of their relationship nod

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
