App Mind

In this section I will demonstrate the logic behind my application which can be visualized as follows.

                        |----------> [messages] ------> [user]
                        |
      |------------> [chats]-------> [pet] ------> [seller]
      |
      |
      |------------> [notifications]
      |
      |             |---------> [reaction] ------> [user]
      |             |
[user/seller]  -> [pet] ------> [comment] -------------> [reaction] -----> [user]
                    |       |        |
                    |       |        |------> [comment] -----> [reaction] ---> [user]
  [location] <------|       |                     |
                            |                     |---------> [user]
                            |--------> [user]

• It all starts with the user or seller

  • anyone who created an account with petmall can buy and sell pets.
  • the user can have access to his/her notifications which are triggered when someone in the app:
    • react to your pet
    • react to your comment
    • commented to your pet
    • reply to your comment on a pet
  • real time messages are the part of this app. The chat models allows buyers and sellers of pets to chat privately. and each chat will be modeled with
    • messages
    • pet
  • The user/seller of the pet can edit pet details and even mark the pet as sold if the pet is sold.
  • an authenticated seller or buyer will have access to the notifications and messages and a profile.
  • In the profile the user can do the following:
    • edit profile details
    • signing out of the app
    • delete their account
    • change account password

• pet model contains the following

  • location of the pet
  • reactions to the pet by others
  • comments / reviews of the pets by others
