这段主要是给一常量字符串赋值的工具类
目的主要是为了在代码的其他地方引用该标识符，以增加代码的可读性和可维护性
封装和提供一组方便的方法，简化对数据库中笔记和相关数据的操作
封装数据库操作的细节，将复杂的数据库操作封装成简单易用的方法
ContentResolver是Android平台提供的一种机制
ContentProvider是用于管理应用程序数据的组件
使用ContentResolver与ContentProvider(Android应用程序中常见的数据库操作方式，可以执行对数据库的查询、插入、更新和删除等操作)
进行交互，执行查询、插入、更新和删除等操作，屏蔽了底层数据库的具体实现细节
该工具类提供了一系列方法，涵盖了常见的数据库操作需求，如批量删除笔记、移动笔记到指定文件夹、查询记录是否存在
可以提高开发效率，简化开发者的工作，使数据库操作更加便捷和灵活
使开发者可以轻松地进行数据库操作，降低开发难度，并提高代码的可读性和可维护性。
