| 2. | 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。 |
| 3. | Entity access matrix documents the effects of each event on the data entities in logical data model
实体接达矩阵记录每项事件对逻辑数据模型内数据实体所产生的影响。 |
| 4. | The general design objectives of the logical data model are correctness , consistency , non - redundancy and simplicity
逻辑数据模型的一般设计目标是正确性、一致性、非冗余和简单性。 |
| 5. | Normalize the ldm using relational data analysis technique . validate ldm against functional requirements as stated in the requirements catalogue
以需求目录所列明的功能需求来核证逻辑数据模型。 |
| 6. | The logical data model of the current environment is extended to support all the processing in the selected business system option
现时环境的逻辑数据模型会扩展至可支援被选取业务系统选择的所有工序。 |
| 7. | Current logical data model provides a logical representation of the relationships between the key entities in the current environment

| 8. | These options may be supported by technical documentation such as work practice model , logical data model and data flow model
这些选择可能需要某些技术性文件的支援，如工作实务模型、逻辑数据模型及数据流程模型。 |
| 9. | Two such viewpoints are represented by data flow modelling ( process point of view ) and logical data modelling ( data point of view )
其中两个审查观点是透过数据流程模型（工序的观点）及逻辑数据模型（数据的观点）来表示。 |
| 10. | Since the ldm is developed to reflect the structure of the data , not all of the relationships identified may be required for functional purposes
由于发展逻辑数据模型的目的是反映数据的结构，因此并非所有认定的关系在功能上都是必要的。 |
