建模和元模型建模概念和技术
时常，建模概念被解释成使用不严密的自然语言。
More often than not, modeling concepts were explained using imprecise and natural language.
随着你经验的增长，如果有必要你可以逐渐引入更强大的建模概念。
As you gain experience, you have the option of gradually introducing more powerful modeling concepts as necessary.
这个建模概念是高级成熟度级别“可消费的类型系统”能力的一部分。
This modeling concept is part of the Advanced maturity level "Consumable Type System" capability.
这些优化后的概念，以不同的方法结合产生了更加复杂的用户级别的建模概念。
These finer-grained concepts are then combined in different ways to produce more complex user-level modeling concepts.
这是一个定义每一种UML建模概念特性和这些特性与其他相关概念直接的关系的模型。
This is a model that defines the characteristics of each UML modeling concept, and its relationships to other modeling concepts.
UML是一种通用语言，因此虽然支持很多建模概念，但是缺乏针对XML的一些概念。
UML is a universal language, so although it supports many modeling concepts it lacks some concepts that are specific to XML.
它因此而引入了一些特定于流程建模领域的建模概念，如关联、补偿、人类用户交互等。
As such it introduces some modeling constructs that are specific to the process modeling domain, such as correlations, compensations, human-user interactions, etc.
特别是，UML建模概念的语义(或含义)的规范，对这些作为自动代码生成或正式确认的基于MDD的活动仍旧是不适当的。
In particular, the specification of the semantics (or meaning) of the UML modeling concepts remained inadequate for such MDD-oriented activities as automatic code generation or formal verification.
本文介绍了一些流程建模概念，通过这些概念分析员可以使用WebSphereBusinessIntegrationModelerV5.1来定义业务流程。
This paper introduced some of the concepts of process modeling that analysts use to define business processes using WebSphere business Integration Modeler V5.1.
但是，为了赋于这种上层结构最大的灵活性，在更高一层上实现重用，我们必须考虑完全按照建模的概念表达这种体系结构。
To give this superstructure maximum extensibility and move the reuse equation up one level, however, we must focus on expressing the architecture completely in terms of modeling concepts.
一旦清楚了底层模型的概念，建模工具使用起来就容易得多了。
Once the concept of an underlying model is clear, the modeling tool becomes much easier to work with.
在我们开始深入的了解mda之前，让我们考虑一下在软件开发中进行建模的基本概念和好处。
Before we delve further into MDA, let's consider the fundamental concepts and benefits of modeling in software development.
如果模型中出现太多重复，那就需要扩展建模语言以覆盖更多的概念。
If there is too much repetition in the models, then the modeling language will need to be extended to cover additional concepts.
假定他们在使用uml建模工作产品、角色和任务的概念。
Imagine that they were modeling the concepts of work product, role, and task using UML.
除了普通的建模规则与可评价的概念，方法必须基于中央的分类以及模型架构的知识。
Besides common modeling rules and a scalable notation, the approach must be based on a central taxonomy and knowledge of modular architecture.
表1描述了被引入到UML 2.0 中的支持 USBD （基于统一场景的设计）概念建模的扩展。
Table 1 describes the extensions introduced to the UML 2.0 to support modeling of the USBD concepts.
建模通过使用业务概念开始，并且以这种方法继续下去。
Modeling starts with business concepts and works its way down.
下一小节描述了被用来支持这些概念建模以及USBD模型结构的实际的UML扩展。
The next sections describe the actual UML extensions that are used to support the modeling of these concepts, and the suggested structure of USBD models.
这些概念在像uml这样的更通用建模语言中并没有涉及。
These constructs are not covered by more general modeling languages such as UML.
数据建模有三层：概念、逻辑和物理。
There are three levels of data modeling: conceptual, logical, and physical.
在概念数据建模阶段，只显示一些作为演示的属性，而在逻辑数据建模期间，必须将每个实体的所有属性包括进来。
Unlike the conceptual data modeling phase, where a few attributes may be shown for illustration purposes only, all of the attributes for each entity must be included during logical data modeling.
有时候，概念数据建模期间表达的关系（特别是多对多关系）在逻辑模型中被显示为实体本身。
Sometimes, relationships expressed during conceptual data modeling (in particular many-to-many relationships) are shown in the logical model as entities themselves.
模型转换概念和技术的建模
构件转换概念和技术的建模。
内在语义描述被建模的资源的“内部含义”，为概念的推演提供基础。
Inherent semantics describe the "inner meaning" of modeled resources and provide the basis for reasoning about concepts.
UML建模的基本概念。
客户机环境按照Web浏览器概念建模，许多控制方式是大家熟悉的，这有助于用户快速地掌握虚拟世界。
The client environment is modeled after the Web browser concept, with many familiar controls to help offset the learning curve of the virtual world experience.
这些是Web服务元数据建模中的重要概念。
Those are the important concepts in modeling Web services metadata.
下面的图一显示了在建模服务时重要的概念。
Figure 1, following, is a diagram showing the important concepts in modeling services.
