project navi/info

src/main/kotlin/com.example.miniBank is where all the packages are

authentication = for jwt authentication to provide security

dtos ←→ controller → service → repository → entity

controller = entry point for http requests (receive requests, process data, determine response)

• GET: retrieve data from a server
• POST: send data to the server to create a new resource
• PUT: update or replace an existing resource
• DELETE: remove a resource from the server

service = business logic (processes data, makes decisions, eg: transferring funds)

repository = database operations (handles communication with db: save, find, delete)

entity = domain model (defines what your data is in the system: fields, relationships)

dto = data transfer object (cleans request/response json bodies, to avoid returning entities)

relationships

• one user, one kyc (know your customer)
• one user, many accounts
• one account, many transactions

services

• register user (username & password)
• log in
• create or update kyc info
• get user kyc info
• create new/multiple accounts
• list accounts
• transfer money to other account
• close account

progress

part 1:

• spring boot setup
• define structure
• database setup
• entities
• repositories
• services
• controllers
• test in postman
• ALL DONE!!!!!!!

part 2:

• as a user, i can log in and get jwt token
• as a developer, i can test:
  • user registration endpoint
  • multiple account creation
  • reading a list of accounts
  • user create profile
  • user update profile
  • user read profile
  • closing a user account
  • transferring money to another account

more notes for understanding

• foreign keys = user_id int references users(id)
• no TransactionController or KycController needed, nor service (because user will only interact with /users and /accounts)
