假设正在开发一个电子商务系统，业务专家使用“订单”来描述用户购买的商品集合。团队可以在代码中使用“Order”来命名相关的类和方法：

type Order = {
    items: OrderItem list
    customer: Customer
    orderDate: DateTime
}

type OrderItem = {
    product: Product
    quantity: int
}

type Customer = {
    name: string
}

type Product = {
    name: string
    price: float
}

let addItem (order: Order) (item: OrderItem) =
    { order with items = order.items @ [item] }

let getTotalAmount (order: Order) =
    let total = 0.0
    for item in order.items do
        total <- total + item.price
    total

let getPrice (item: OrderItem) =
    item.product.price * item.quantity

let getTotalPrice (order: Order) =
    let total = 0.0
    for item in order.items do
        total <- total + getPrice(item)
    total

在这个示例中使用了“Order”、“OrderItem”、“Customer”和“Product”等术语，这些术语都是 Ubiquitous Language 的一部分，可以提高代码与业务需求的一致性。
