This article later describes a real-life case study on using a LDM as the semantic source and transforming it into various IT artifacts.
本文稍后将介绍一个真实的案例分析，研究使用LDM作为语义源并将其转换为各种IT工件。
5
LDM Entities and Attributes and their descriptions are often either derived from, or later become, an organization's business vocabulary.

6
This article describes an example use case in which a UML modeler is transformed into a logical data model (LDM).
本文将描述一个示例用例，其中，一个UML模型将被转换为一个逻辑数据模型（LDM）。
7
Business items could become a basis for defining the Logical Data Models (LDMs), if a LDM does not exist for that business domain.
如果某个业务域没有现成的LDM，那么可根据业务项定义逻辑数据模型（LDM）。
8
The data modeler transforms part, or the whole, of an LDM into a class model using the LDM-to-UML transformation.
数据建模师使用LDM到UML转换将LDM的全部或一部分转换成一个类模型。
9
Transforming an LDM specification to a UML model is an equally valid and supported use case.
将一个LDM规范转换为一个UML模型也是一个同等有效和受支持的用例。
10
Some semantics may be lost during transformation from LDM to business items because LDM holds richer semantics than business items.
在从LDM转换到业务项时可能会丢失一些语义，因为LDM语义要比业务项语义丰富。
11
It is not an exaggeration to say LDM is the semantic hub of enterprise architecture.
将LDM称为企业架构的语义中心并未夸大其辞。
12
In the following section, you apply stereotypes for the Skyway DSL transformation and for the LDM transformation.
在接下来的部分中，您可以对SkywayDSL转换以及LDM转换应用模板。
13
This interchange of content is supported through the UML-LDM and LDM-UML transforms that are available with RDA and RSA.
这种内容的互换是在RDA和RSA提供的UML-LDM和LDM-UML转换的支持下进行的。
14
A distant fourth would be a detailed logical data model (LDM).
第四位的是详细的逻辑数据模型（logicaldatamodel，LDM）。
15
Similarly, changes to this UML model, perhaps based on business use cases in RSA, can be imported as updates to the LDM in RDA.
类似地，对这个UML模型的更改（也许是基于RSA中的业务用例）可以被导入，作为对RDA中LDM的更新。
16
were frequently overlooked in the software development life cycle, but they become increasingly more important in SOA for many reasons.
在软件开发生命周期中，逻辑数据模型（LogicalDataModels，LDM）常常被忽略，但是出于多种原因，它在SOA中的地位变得日益重要。
17
Previous studies shown that LDM have could inhibit the proliferation and migration of endothelial and tumor cells.
研究发现LDM对多种内皮细胞、肿瘤细胞有显著的抑制效果。
18
Data models may become so tightly coupled with particular business processes that future projects need to modify a LDM significantly.
由于数据模型可能会与特定业务流程紧密耦合，以至于将来的项目需要对LDM进行大量修改。
19
If you simply push LDMs into process models without appropriate communication, the details might overwhelm business analysts.
如果未经恰当交流就将LDM推入流程模型中，那么业务分析师将会面对大量的信息。
20
Look at HOME. ldm within the Data Project Explorer window and the tables and data that describes this database.
看一下DataProjectExplorer窗口中的HOME.ldm以及描述这个数据库的表和数据。
21
For the LDM transformation you have to tag this domain object as an entity stereotype.
对于LDM转换，您必须将这个域对象标记为实体构造型。
22
Because LDMs tend to be more complete than business items, with more fields or properly normalized entities.
由于LDM一般比业务项更加完整，具有更多字段或正确标准化的实体。
23
it is important to get user acceptance of the accuracy of each ldm . document the ldm.
向用户展示逻辑数据模型；要用户接受每个逻辑数据模型的准确性是重要的。
24
Data modeler compares and merges LDM baseline one and two in Rational Data Architect.
数据建模师在RationalDataArchitect中比较并合并基准1和基准2。
25
The extra cost of LDM can be more easily shared.
可以更加轻松地分担额外的LDM成本。
26
A LDM helps to reduce total cost of ownership.
LDM有利于减少总体拥有成本。
27
A good data modeler is worthy of investment so you should hire someone or develop people internally with LDM skills.
优秀的数据建模师值得企业为其投资，因此，您应该雇用拥有LDM技术的人员或在内部进行培训。
28
The potential value of LDMs is that they provide a technology independent overview of the business entities supported by your DW.
LDM的潜在价值是它们提供DW支持的、对业务实体的技术独立概述。
29
If business analyst doesn't understand LDMs, they may end up repeat information and define entities or attributes that are already in LDMs.
如果业务分析师没有正确理解LDM，他们可能会生成重复的信息并定义LDM中已经存在的实体或属性。

To execute the transformation, click Run, which creates an LDM file corresponding to the UML model, such as Involved Party. ldm.
要执行这个转换，单击Run，这将创建一个对应于UML模型的LDM文件，比如InvolvedParty.ldm。
