数据及文件通常有三种类型：
- 配置文件型：如ini，conf，properties文件，适合存储简单变量和配置项，最多支持两层，不适合存储多层嵌套数据
- 表格矩阵型：如csv，excel等，适合于存储大量同类数据，不适合存储层级结构的数据
- 多层嵌套型：如XML，HTMl，JSON、YAML，TOML等，适合存储单条或少数多层嵌套数据，不适合存储大量数据
YAML兼容JSON格式，简洁，强大，灵活，可以很方便的构造层级数据

可扩展标记语言（Extensible Markup Language (opens new window)，简称：XML）是一种标记语言。
标记指计算机 (opens new window)所能理解的信息符号，通过此种标记，计算机 (opens new window)之间可以处理包含各种信息的文章等。
如何定义这些标记，既可以选择国际通用的标记语言，比如HTML (opens new window)，也可以使用像XML这样由相关人士自由决定的标记语言，这就是语言的可扩展性。
XML是从标准通用标记语言（SGML） (opens new window)中简化修改出来的。 它主要用到的有可扩展标记语言、可扩展样式语言（XSL） (opens new window)、XBRL (opens new window)和XPath (opens new window)等
Simple API for XML（SAX） (opens new window)是个循序存取XML的解析器API，非W3C官方所提出的标准，它是事件驱动的（一种基于回调
callback机制的程序运行方法）。 它是除了文档对象模型（DOM） (opens new window)的另外一种流行选择，DOM需要读入整个的XML文档，然后在内存中创建DOM树，生成DOM树上的每个Node对象
