第二种创建模型的方法如下所示。
我们将分三个阶段创建模型。
用于创建模型的对象关系映射
现在，您已经准备好为小部件创建模型。
创建模型实例时可以包含需要的任何数据。
You can include any data you want when you're creating a model instance.
我们准备好创建模型后，单击Start。
创建模型片段并将它们添加到源代码控制下。
如果要从现有的DDL文件创建模型，就选择ddl脚本。
Choose DDL script if you are creating a model from an existing DDL file that you have.
不过，创建模型的调用是一个不具有任何返回值的存储过程。
The call that creates a model is, however, a stored procedure that does not have any return value.
我们从基本操作开始：从头创建模型并向其添加rdf语句。
Let's start with the basics: creating a model from scratch and adding RDF statements to it.
现在可以开始查看这些组件的运作，并开始创建模型导航插件。
We are now ready to see these components in action and begin to create our model navigation plug-in.
没有关系支持：创建模型实例就意味着只能编辑实例的基本属性。
No relationship support: creating a model instance means you are just editing the basic properties on that instance.
不了解有关创建模型和内容的实践，从而造成内容具有不可持久性
Not knowing about this practice upon model or content creation, causing the content created against the model to be non-durable.
创建模型的最后一个步骤是选择因变量(即我们想要预测的列)。
Finally, the last step to creating our model is to choose the dependent variable (the column we are looking to predict).
创建模型的第一步就是定义EMF 模型的协作对象。
The first step on our adventure is to define an EMF model with which to work.
如果您决定在创建模型之后更改这些特性，可以简单地这样操作。
If you decide to change the capabilities after creating the model, simply.
指定需要通过对DB 2 9.7数据库进行反向工程来创建模型。
Specify that you want to create the model by reverse engineering a DB2 9.7 database.
该命令将创建模型-视图-控制器(mvc)的视图和控制器部分。
This command creates the proverbial view and controller part of Model-View-Controller (MVC).
要创建模型，先切换到ModelView并展开最上面的叶子。
To create the model, switch to model View and expand the top-most leaf. You'll see three further leaves at the next level.
如图2所示，一个为该产品创建模型的期望分析人员会将公司作为域。
As Figure 2 shows, an expectation analyst creating a model for this project would treat the company as the domain.
在理想的世界中，业务分析人员创建模型以表示某个流程需要做的工作。
In an ideal world, a business analyst creates a model to express what a process needs to do.
因为我们在创建模型，我房子的价格还不知道，所以我们还不能输入我的房子。
Since we are creating the model, we cannot input my house into it since the selling price is unknown.
所有对子单元元素的应用都会自动升级到从子单元中创建模型的元素。
All the references to the elements of the subunits are automatically updated to the elements of the model created from the subunit.
我们的简单模型只需定义一个面板和一些创建工具来辅助创建模型(参见图6)。
Our simple model only needs to define a palette and some creation tools to help with model creation (see Figure 6).
当您在创建模型片段时，您会创建一个小的文件，该文件包含了片段的模型元素。
When you create a model fragment, you create a small file that contains the fragmented model elements.
在基本编辑模式中工作，可以加快模型的编辑速度，尤其是从头创建模型的时候。
Working in basic editing mode speeds up editing models, especially when creating models from scratch.
创建模型以后，如果您决定模拟该流程，则会遇到一个问题：如何运行多个模拟呢？
After creating the model, if you decide to simulate the process you have a problem: how can you run multiple simulations?
除此之外，你可以创建模型(服务器的抽象表述)，并把它们克隆到多个JVM中。
In addition, you can create models (abstract representations of a server), which are then cloned into multiple JVMs.
是否你正在试图创建模型，我不知道，一种特殊药品的功效，你们要经过一些入门步骤。
If you are trying to model, I don't know, the efficacy of a particular drug, these are the baby-steps that you will go through.
在基本编辑模式中工作，可以加快模型的编辑速度，尤其是从头创建模型的时候。
So the analyst has created a simple process that you need to update, using Basic mode in Modeler.
