该应用程序正在记录将保存在 firebase 中的糖尿病血糖读数，它还可以检索读数以显示图表格式的进度.

the application is recording the diabetes glucose reading which will be saved in firebase and it can also retrieve the readings for showing the progress in chart format.

请问有人可以帮我吗?

推荐答案

不，数据库不应包含在隔离系统的用例图中.数据库是系统的静态内部部分，在没有前端接口(即您的系统本身)的情况下不会直接参与.

No, databases should not be included in a Use Case Diagram of an isolated system. Databases are a static internal part of a system and do not directly take part without a front interface (i.e. your system itself).

但是，如果您的数据库是一个外部实体，即它在不同系统之间共享，那么将其显示为演员可能是明智之举.

However, if your database is an external entity i.e. it is being shared between different systems then maybe it would be wise to show it as an actor.
