有人可以帮我纠正我的联想吗?
我有以下型号:
User,Developer,Application,Comments,Rating,Permission
要求:
A user can be a Developer or not. A user can have Default Permissions and Permissions for each application A user can install multiple Applications A user can comment and rate multiple Applications A developer can develop multiple applications An application can request a list of permissions.
我已经创建了一些关联,但我相信它不是100%正确或更简单的方法存在.
有人可以建议我这样做的正确方法吗?
