我将一次回答您的几个问题：
Bigtable 是构建 AppEngine 数据存储区的系统。它实际上是一个分布式哈希表。
需要进行身份验证，因为您必须拥有 Google 帐户；您必须已注册 AppEngine；您必须已经在 AppEngine 中创建了一个应用程序。您的应用程序将能够访问数据存储区，如果您登录到应用程序的管理控制台，则可以使用数据存储区查看器检查应用程序数据存储区的内容。
数据将存储在谷歌服务器上。
本身没有表，但您可以使用数据存储查看器来查看驻留在应用程序数据存储中的实体。
不可以，您永远无法查看其他应用程序创建的数据存储区的内容。每个应用程序的数据存储区视图都是完全孤立的，并且与其他 AppEngine 应用程序的视图没有任何连接。
I'll take your several questions one at a time:
Bigtable is the system on which AppEngine's datastore is built. It is effectively a distributed hashtable.
Authentication is required in that you must have a Google Account; you must have signed up for AppEngine; you must have created an application within AppEngine. You application will be able to access the datastore, and if you are logged in to your application's Admin Console, you can use the Datastore Viewer to inspect the contents of your application's datastore.
The data will be stored on Google Servers.
There are no tables, per se, but you can use the Datastore Viewer to view entities that reside in your application's Datastore.
No, you can not ever view the Datastore's contents that were created by other applications. Each application's view of the Datastore is completely siloed and has no connection to that of other AppEngine applications.
