面向对象的

The implementation of object algebra by relational operator and spatial operator with the support of relational index and spatial index was discussed and the setoriented access methods were studied.

在系统实现方面，我们着重讨论了面向集合的对象存取方式及基于关系索引、空间索引和底层关系操作及空间操作的对象代数的实现机制。

The application of information share and WWW method in NCCAD is studied to ingeniously present and achieve the DC model of engineering CAD information based on Object-Oriented and drawing hyperlink, which maps the restrict and topology of product information to intra-conjunction and inter-hyperlink of DC Object .

研究信息共享和WWW模式在网络CAD环境中的应用，基于面向对象技术和图形链接技术创造性地提出并实现了工程CAD信息的图元模型，将产品信息模型的约束与拓扑关系映射为图元对象内部关联和外部链接两个层次。

ANF〓 model combined with object-oriented features is used as ANGEL's data model. That makes ANGEL to be able to not only describe the complex objects directly and correctly, but also manipulate them conveniently and pleasedly.

该系统独创性地采用了非一范式结合面向对象特征的数据模型，从而既具备直接而准确地描述复杂对象结构的能力，又具备方便而快捷的数据操纵能力。

With the object-oriented technology, an object is a single entity in which data and methods are capsulized. It can be used to represent knowledge or entities in simulated domain.

在面向对象技术中，对象能在单个实体中封装数据和操作，并为知识和被模拟领域中的实体的表示提供条件。

Firstly, this paper analyzes the merit and the demerit of the process-oriented development methodology and the object-oriented development methodology. After comparing the development methodology base on MDA to the others, it is pointed out that the development methodology based on MDA has great advantage over others because it can address those mentioned problems which have been fazing software developers in long terms.

本文首先分析了面向过程方法和面向对象方法在开发模式上各自的优点和局限性，并将基于 MDA 的开发模式同前两种开发模式进行对比，针对这些局限性阐述了基于 MDA 的开发模式相对于这两种开发方法的优势，指出 MDA 可以很好的解决不同平台重复建模、不同平台无法互操作等一系列问题。

The design theory idea Object Relation mapping solved the mismatching problem between object-oriented design and relational database model.

对象映射关系数据库的设计思想解决了面向对象程序设计和关系数据库不匹配的问题。

Chapter Ⅴ renders the way the correspondent object model is supported on the level of operating system and the prototype of the DOOS.

第五章讨论了如何在操作系统中支持相应的对象模型，介绍了一个分布式面向对象系统的原型设计。

A new method for constructing a heterogeneous distribured information system is introduced as result of the application of Object-oriented method.

面向对象方法在分布系统中的使用，形成了一种构造分布信息系统的新方法，即分布对象管理方法。

A new method for constructing a heterogeneous distributed information system is introduced as result of the application of Object-oriented method.

中文摘要：面向对象方法在分布系统中的使用，形成了一种构造分布信息系统的新方法，即分布对象管理方法。

The platformis characterized by client/server model, using object--oriented method to cope withheterogeneity, separating tailorable policies from mehanisms of coordinatioordination, sothat it can provide flexible and convenient service for the cooperative applicationsupported by some basic distributed functions, such as I/O,data transmission andso on.

本文提出了一个CSCW系统的结构模型，该结构以一个CSCW支撑平台作为一般分布式系统与协作应用之间的适配层，来支持协作任务，平台具有客户／服务器模式，它用面向对象方法处理各种异构性，将协作规则与协作机制分开，这样它就可以仅利用基本的分布功能，提供方便灵活的面向用户协作的服务。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
