1、单体（数据）映射：基本操作；数据的单次映射；
2、管道流：数据的流程化处理
基础是monand类型，形式是声明式编程；
Pipeline模型：
它以一种“链式模型”来串接不同的程序或者不同的组件，让它们组成一条直线的工作流。这样给定一个完整的输入，经过各个组件的先后协同处理，得到唯一的终于输出。
pipeline（管道）借鉴于 Unix Shell 的管道操作——把若干个命令串起来，前面命令的输出成为后面命令的输入，
面向（monad）类型的编程：类型是流上的节点；
类型的上下转换、类型对pipeline的串联；

Monads allow a programming style where programs are written by putting together highly composable parts, combining in flexible ways the possible actions that can work on a particular type of data. As such, monads have been described as "programmable semicolons"; a semicolon is the operator used to chain together individual statements in many imperative programming languages,[2] thus the expression implies that extra code will be executed between the actions in the pipeline. Monads have also been explained with a physical metaphor as assembly lines, where a conveyor belt transports data between functional units that transform it one step at a time.[3]
