A community is a group that emerges from a network of relationships. Though structurally, any instance of an application limits who has access to application data, communities ultimately aren’t predefined just by their app data.
社区是从关系网络中出现的群体。尽管在结构上，应用程序的任何实例都限制了可以访问应用程序数据的人员，但社区最终并不仅仅由他们的应用程序数据预定义。
