MDSplus的是分层结构，其中基础的数据的结构是树形（TREE）结构。大量的节点（NODES）组成树的分支和叶子。MDSplus中的SHOTS是由模型树创建的副本。个人理解: 每个SHOT都是从model tree拷贝过来的模版，然后添加各自的数据。
1.节点自描述的特性
2.树和文件的关系
3.数据类型
4.表达式
5.本地和远程
5.some mdsp api
Tress structure
=>top hierarchy is the name of the tree,next is child nodes,underneath them is members node.This kind of hierarchy as analogous to the directories and files on a os
=>three ways to uniquely specify a node in a tree ,the full path name,a relative path nameand a tag name
full path name: \treename::top.child1.child2:member
Data types
=>single/double/signal/device,and so forth
Expression
some basic operation:plus/multiply,and so forth
