Best practice for using ASPNETDB in combination with another database

Need to add users/roles etc to my web application. I want to use aspnetdb, because other web applications will need the same thing. I do not want to merge these tables into my db, either for the same reason. But, in my database I have tables that store informa开发者_JS百科tion related to the user that I want to access.

e.g.

MealTable Id, UserId, MealName, Calories

So what's the best way to handle this?

I think the best way is the way you seems that you use it.

Use the UserId to connect your users in your application with the aspnetdb that keep the users.

Now if you like to keep yours application robust when you go to delete a user, you need to search all your other database application to see if this is possible/permited.
