DDD how to define bounded contexts

0
votes

An application "School" should have three types of users: Pupil, Parent, Admin.

  1. Admin can register children in the school (they becomes Pupils) and attach parents to him/her; create a school schedule
  2. Pupil should see the school schedule and his/her marks
  3. Parent can watch marks of his/her children who are Pupils in the school; pay school fees

Could you help me to define bounded context(s) for this application? For me it's look like here is more than one bounded context.

At first, you have to think about the autonomy Of Bounded-Context. The next thing is about transactions. You have to think about the independent transactions as you can. Each Bounded-Context must have its world and ven its language (Ubiquitous Language).

With This info and more info, you can decide about Bounded-Context better. According to your information, I think It could have 3 Bounded-Contexts:

  1. School Schedule
  2. School Finacial
  3. Users-Area (Authentications or profile)

Just keep in mind all Bounded-Contexts (ex: Schedule) should work independently without other Bounded-Contexts (ex: Users-Area). for example you can have Name and family and UserId in Schule Schedule Bounded-Context. But the whole data of the user is in Users-Area Bounded-Context(like Profile data) and when you need it you can get data from it in a few ways.
