The Draft Business Rules have been defined and are listed below.
User Requirements :-
A design to store Preference Settings in a database.
Let's assume 3 levels
1) a general (= default settings)
2) group level
3) user level - a user belongs to a group.
Group- and User- settings overwrite the general settings and are normally a
subset of all possible values.
----------------------------
this could be an example:
general:
- color = black
- lang = en
- size = 5
group1:
- lang = fr
user1:
- size = 6
(user1 belongs to group1)
----------------------------
the query to get all the settings for user1 should return the following
values:
- color = black
- lang = fr
- size = 6
----------------------------
I know, there are other solutions than using a database and it could be a
massive overkill, but I'm interested in possible designs.
Thank you for any comment!
