An OVUM report published in 1988 predicted that database systems adhering to an object-oriented data model as opposed to a relational data model would overtake relational database systems by the mid 1990s (OVUM, 1988). Although this clearly has not happened, there is no doubt that object-...

LOOM (landslide object-oriented model) is here presented as a data structure for landslide inventories based on the object-oriented paradigm. It aims at the effective storage, in a single dataset, of the complex spatial and temporal relations between landslides recorded and mapped in an area and...

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
OptimizationTranslatingThe high level object oriented data model TM, based on an extension of the typetheory of Cardelli, is addressed. TM includes a logical formalism for constraint specification, which is an important aspect of the data model, and the notion of predicative sets. Predicative set...
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. ...
