Windows 8 HTML5/Javascript 桌面开发中的 SQL 数据访问
尊敬的开发界圣贤们大家好，
我谦卑地向您提出一个菜鸟问题。事实上，我对 Windows 8 Metro HTML5/Javascript 开发感到非常兴奋，但我还没有深入研究它。谷歌到目前为止让我失望的第一个问题是如何使用 Metro HTML 应用程序进行本地数据访问？我知道我可以使用一些新的 HTML5 本地存储功能，但是如果我希望有一个应用程序能够写入/接收数据以表示本地计算机上的 SQL CE 数据库而不是远程数据库，我该怎么说呢？是否有某种可编程的内置对象，我可以使用 Javascript 访问它来进行数据操作，从而取代 Web 服务器的传统位置？
谢谢您的宝贵时间。
Hi exalted sages of the development world,
I humbly come before thee with a noob question. I'm actually pretty excited about Windows 8 Metro HTML5/Javascript development, but I haven't dived in to it yet. One initial question that immediately came up that Google has failed me on so far is how do I do local data access with metro HTML apps? I understand that I can use some of the new HTML5 local storage features, but what do I do say if I want to have an application that writes/receives data to say a SQL CE database on the local machine as opposed to a remote one? Is there some kind of programmable built in object that I can access with Javascript to do data manipulation with that would take the traditional place of a web server?
Thank you for your time.

WinRT 中没有用于 SQL 访问的客户端。要访问此类数据库，您必须创建一个 Web 服务并调用它（类似于 Silverlight）。 WCF RIA 服务为此提供支持。
要在本地存储和检索数据，可以使用 JET API。 HTML 和 JavaScript 应用支持 IndexedDB。所有这些选项都会将数据读取和写入到应用程序的独立存储中；它们不允许自由访问文件系统。
