摘要

CalcuList(带有列表操作的计算器)是一种用于教授函数式编程的教育语言，扩展了一些命令式和副作用特性，这些特性在程序员的明确要求下启用。除了字符串和列表，该语言本身也支持json对象，并且可以有效地用于实现通用MapReduce递归过程来操作json列表。MapReduce是分布式计算中的一个流行模型，它支持许多NoSQL系统，json列表可以被认为是文档NoSQL数据存储的数据集。事实证明，CalcuList可以用作教授文档数据存储(如MongoDB和CouchDB)的高级查询算法的工具。

Using CalcuList To MapReduce Jsons

CalcuList (Calculator with List manipulation), is an educational language for teaching functional programming extended with some imperative and side-effect features, which are enabled under explicit request by the programmer. In addition to strings and lists, the language natively supports json objects and may be effectively used to implement generic MapReduce recursive procedures to manipulate json lists. MapReduce is a popular model in distributed computing that underpins many NoSQL systems and a json list can be thought of as a dataset of a document NoSQL datastore. It turns out that CalcuList can be used as a tool for teaching advanced query algorithms for document datastores such as MongoDB and CouchDB.
