like the e-r model,the object-oriented model is based on a collection of objects. an objects contains values stored instance variables within the object. an object also contains bodies of code that operate on the object. these bodies of code are called method.
objects that contain the same types of values and the same methods are grouped together into classes. a class may be viewed as a type definition is similar to programming language abstract data type(adt).

帮我翻译一下好么 线上等

哎，你这要找洋文高手而不是VFP高手，看样子你敲错房门了。。

一个对象包含存储的值在对象以内的实例变数。 一个对象也包含代码的本身运行对象。 代码的这些本身被称为方法。
对象那包含值的一样的类型并且一样的方法一起封装成类。 作为一个类型定义类可以被看相似于程序语言抽象的数据类型

谢谢~~~
