有没有在ASP.NET动态数据框架（DDF）任何真实世界的案例研究？ [英] Are there any real-world case studies on the ASP.NET Dynamic Data Framework (DDF)?

问题描述

我刚刚结束了一个拱形的审查和下一代的建议为我们的客户需要约我见过一个应用程序定制的最深层次。他们的愿望是从UI定制自己企业的Web应用程序后端按客户（40+客户需要控制级定制）。定制甚至会包括一些特殊的业务规则引擎和非常复杂的逻辑，涉及交通运输行业。尽可能是可能的，他们通过这样的定制可以通过他们的客户其开发者来驱动，并具有最小没有参与自动化一切要开发的佳境。

I just wrapped up an arch review and next-gen recommendation for a client of ours that needs about the deepest level of customization I’ve ever seen for an application. Their desire is to customize their enterprise web application from the UI to the back-end by customer (40+ customers needing control-level customization). The customization will even include special business rules engines and very complex logic involving the transportation industry. As much as is possible, they want developer nirvana by automating everything so customizations can be driven by their customers and have minimal to no involvement by their devs.

，虽然有将需要建造以及安全一些额外的管道，该DDF将让他们更接近自己的目标比什么都在那里了。然而，他们要求比我为他们提供更详细的信息。

Based on my research, though there will need to be some additional plumbing built in as well as security, the DDF will get them closer to their goals more than anything else out there. However, they're requesting more detailed information than what I provided for them.

我真的需要一个个案研究或一个企业级的公司已经成功地实施了DDF，并给出细节，它解决了他们的问题，企业的其他类似的证词。任何指示或帮助将非常是AP preciated。谢谢！

I really need a case-study or some other such testimony of an enterprise-level company that has successfully implemented the DDF and gives details as to the enterprise problems it solved for them. Any direction or help would very much be appreciated. Thanks!

推荐答案

好了谨慎的至少一个字。 DDF的一个重要方面（和卖点）是元数据的分配属性，以帮助支架列和表以及使用新的动态数据控件获得元数据的优势（如QueryableFilterUserControl或DynamicDataManager或PageAction）。但是元数据的一个方面是，它被分配在运行时，一旦应用程序已启动，不能操纵。因此，不同的用户就都可以登录到基本相同的元数据集，并定制基于用户的将是一场噩梦。您可以根据组的角色设置一定的安全性和权限，但控制的高级定制将是困难的。我希望这有助于。

Well at least one word of caution. One important aspect (and selling point) of DDF is the assignment of metadata attributes to help scaffold columns and tables and the use of new dynamic data controls to gain advantage of that metadata (like QueryableFilterUserControl or DynamicDataManager or PageAction). One aspect of metadata however is that it is assigned at run time, and cannot be manipulated once the application has started. Therefore different users would all be logging into basically the same metadata set, and customization based on user would be a nightmare. You can certainly set security and permissions based on group roles, but control level customization would be difficult. I hope this helps.
