}

entity Customer {
    name : string[32]
    age: int
    payment: string[32]
    address: address
    orders -> Order."Order.customer"[0..*]

    customer -> Customer."Customer.orders"[1]
}

entity Review {

//source and target have X common reviews
entity CommonReviews {
    count : int
    source -> Customer[1]

relationaldb ECommerce {
  tables {
    table { OrderTbl : Order }
    table { 
      CustomerTbl : Customer
      index nameIdx { attributes ("name") }
    }
