    Is this a correct design for a user and client relation?

    I'm building a database in which.

    > A Client has phases that belong to them, A client can have a 'design-phase', 'development-phase'. Now a Client has many users, and these users can be assigned phases. But only the one's their parent (the client) has offcourse. **All Clients should by default have every phase assigned to them that their parent has, so that's why I'm thinking about the client_blocks table**

    Now I'm wondering if my database design is correct, It feels like something is off.

    - Does my database need to worry about which phases are part of this client, or on creating a user, should I copy over the phases that are assigned to his parent, the client?

    Any help in the right direction would be greatly appreciated!
    Thank you

    then you need a relationship between user_blocks and client_blocks to enforce this
