Without a solid background on object oriented design, we can quickly get lost in a world of objects, relations and classes.
如果没有坚实的面向对象设计基础，我们很快就会迷失在对象、关系和类的世界里。

It called for developers to create little building block classes and objects and glue them together to produce the final application.
它提倡开发人员建立类和对象，并将它们结合起来以产生最终的应用程序。
Further decomposition lets us start identifying additional objects that can be modeled into classes, and other objects within the design.
对它进行进一步的分解，我们就可以开始确定可以建模为类的额外对象和设计中的其它对象。
This article assumes you are familiar with basic object-oriented concepts, such as classes, objects, methods, and inheritance.
本文假设读者熟悉基本的面向对象概念，比如类、对象、方法和继承。
Starting with our use case and list of classes, we choose objects from those classes to interact, and we construct a SQD to show that interaction.
从用例和类表出发，我们从类里选择需要交互的对象，然后构造一张序列图表示这种交互。
That is, tables map to classes, objects map to rows, and object properties map to columns.
换句话说，表映射到类，对象映射到行，而对象属性映射到列。
Identify the objects, the unintentional references, the classes and objects holding those unintentional references, and the objects to which the unintentional references are pointing.
确定对象、无意引用、保留这些无意引用的类和对象以及无意引用指向的对象。
Because patterns do not only affect the structure and dynamics of classes and objects, this article will conclude investigating the role of patterns in a service-oriented architecture (SOA).
由于模式不只是影响类和对象的结构，还有动态(操作)，所以这篇文章将会对在面向服务的体系架构(SOA)中模式所承担任务的调研得出结论。
If the application persists serializable objects externally and changes are made to the classes for these serializable objects, then special consideration needs to given to the changes.
如果应用程序持续使用可串行化的对象，并且会对这些可串行化的对象的类做出改变，那么在做出这些改变的时候要加以考虑。
