上面的英文摘自<Graph Databases>(作者:IanRobinson) 一书,描述了 neo4j 的存储模型。Node和Relationship 的 Property 是用一个 Key-Value 的双向列表来保存的; Node 的 Relatsionship 是用一个双向列表来保存的,通过关系,可以方便的找到关系的 from-to Node. Node 节点保存第1个属性和第1个关系ID。

在 Java 程序中可以通过嵌入的方式来启动 Neo4j 数据库，只需要创建 org.neo4j.kernel.EmbeddedGraphDatabase 类的对象，并指定数据库文件的存储目录即可。在使用 Neo4j 数据库时，进行修改的操作一般需要包含在一个事务中来进行处理。通过 GraphDatabaseService 接口的 createNode 方法可以创建新的节点。Node 接口的 ...
