Groundwork for an Object-Oriented Database ModelBeech, D
Formally, an object-oriented database model is a tuple (CS,AS,RS,O,M,S), in which CS is a finite set of classes, AS is a finite set of attributes, RS is a finite set of relationships, O is a finite set of objects, M is a finite set of methods, and S is a finite set of...
Object Oriented Database Model Object Oriented Database Model Represents an entity as a class Represents an entity as a class A class captures both attributes and behavior A class captures both attributes and behavior Instances of the class are called objects Instances of the class are called objec...
To full fill this, we developed an object oriented database tool to retrieve and store the GEOMETRY model data from a STEP file using JAVA. This tool operates around a model that uses a well-defined configuration management strategy to manage and storage of GEOMETRY data....

Object-OrientedModel(OOM) 面向对象模型,一个OOM包含一系列包,类,接口 , 和他们的关系。 这些对象一起形成所有的 ( 或部份) 一个软件系统的逻辑的设计视图的类结构。 一个OOM本质上是软件系统的一个静态的概念模型。 (1)利用UML描述系统结构 (2)利用类图生成不同语言的源文件(如Java、C#、PowerBuilder等),...
Abstract The aim of this paper is to show that a wide class of AI applications can be directly supported by Object-Oriented database technology. The class of AI applications addressed is that of Terminological Systems, such as KL-One and Back, characterized by Frame Definition Languages. ...
以前一直是通过powerdesigner 的Object Oriented Model生成数据库表,再通过代码生成器生成nhibernate实体类,映射文件。感觉不是很直接。 使用powerdesigner 15的内置功能,就可以生成nhibernate的数据访问层。不过默认的用在实际环境中不是很好,可以改一下模板生成自已需要的。下面是实际步骤。

GIS (geographic infortnation system) data can be divided into three sorts: geometric data, geographic data and graphic data. TLDM proposed in this paper describes these three sorts of data and their relationships with object-oriented model. TLDM is used
