generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "sqlite"
  url      = env("DATABASE_URL")
}

model Books {
  id                Int     @id @default(autoincrement())
  isbn              String  @unique
  title             String
  author            String
  description       String
  genres            String
  publishedDate     String
  pageCount         Int
  imageUrl          String
  price             Float
  sales             Int
  availableQuantity Int
  sellerID          Int
  Sellers           Sellers @relation(fields: [sellerID], references: [id], onDelete: Cascade, onUpdate: Cascade)
}

model Sellers {
  id          Int     @id @default(autoincrement())
  firstName   String
  lastName    String
  username    String
  password    String
  role        String
  bankAccount String
  companyName String
  books       Books[] //books the seller is selling
}

model Customers {

  firstName     String
  lastName      String
  username      String

  street        String
  city          String
  country       String
  zipCode       String
  purchaseditem purchasedItem[]
}

model purchasedItem {
  id     Int @id @default(autoincrement())
  userId Int

  itemsPurchased Item[]

  Customers   Customers? @relation(fields: [userId], references: [id])
  
}

model Item {
  isbn            String        @unique
  quantity        Int
  imageUrl        String
