是否有任何标准或“最佳做法”方法限制特定应用的特征功能?

例: 我们的产品具有各种特点,我们的客户可以选择和选择他们希望使用哪些特征,产品成本也因实际使用的特点而有所不同。

过去,我们与我们的软件安装商一道,分发了一份加密的许可证文件,其中载有关于客户的信息,并收集了他们能够做到的特征。在编码中,我们从许可证档案中读取,并根据许可证档案使这一功能成为可能。

看来,除了有一些不利之处外,这似乎还很出色:

Upgrading users with new functionality can be sort of a pain
If a particular feature shows up in multiple places throughout the application, a developer might not realize that this feature should be licensed, and forget to check the license file before granting functionality to the user
If the license file becomes corrupted, deleted, moved, renamed, etc. the application will not run

我们重新准备推出一套新的特征,我很奇怪,社区其他人为解决这一问题做了些什么?

Answer 1

通常有三种共同办法:

using fixed program versions (each version just adds features, you can t customize which features you want or not). You can use also "subversion", like basic and pro edition for Software x.0. Windows uses this approach.
Having modules of functionality, which are a product as themselves. Matlab uses this approach.
Having a software with basic functionality, and then having plugins, or extra apps for sale. Eclipse uses this approach (though it s free)

你们也可以把这些办法结合起来,以更好地适应需要。

Answer 2

为什么不将产品分解成像Matlab这样的模块? 然后对每个模块收费。许可证可以在线保存,终端用户只需下载该单元,以备该功能。
