当实体包含过多的信息时,可以通过拆分实体的方式来解决。以下是一些解决方法的示例:
class Order:
def __init__(self, customer, items, payment):
self.customer = customer
self.items = items
self.payment = payment
class Customer:
def __init__(self, name, address, phone):
self.name = name
self.address = address
self.phone = phone
class Item:
def __init__(self, name, price, quantity):
self.name = name
self.price = price
self.quantity = quantity
class Payment:
def __init__(self, method, amount):
self.method = method
self.amount = amount
class Address:
def __init__(self, street, city, state, zip_code):
self.street = street
self.city = city
self.state = state
self.zip_code = zip_code
class Customer:
def __init__(self, name, address, phone):
self.name = name
self.address = address
self.phone = phone
class Order:
def __init__(self, customer, items, payment):
self.customer = customer
self.items = items
self.payment = payment
class Item:
def __init__(self, name, price, quantity):
self.name = name
self.price = price
self.quantity = quantity
class Payment:
def __init__(self, method, amount):
self.method = method
self.amount = amount
class Order:
def __init__(self, customer, payment):
self.customer = customer
self.payment = payment
self.items = []
def add_item(self, item):
self.items.append(item)
class Item:
def __init__(self, name, price, quantity):
self.name = name
self.price = price
self.quantity = quantity
class Customer:
def __init__(self, name, address, phone):
self.name = name
self.address = address
self.phone = phone
class Payment:
def __init__(self, method, amount):
self.method = method
self.amount = amount
通过以上的解决方法,可以有效地减少实体的信息量,使实体更加简洁和易于维护。
