用RM-ODP工程语言实现数据库管理系统
Specifying Data Bases Management Systems by Using RM-ODP Engineering Language
摘要：
分布式系统可能非常庞大和复杂。影响其设计的各种考虑因素可能会导致大量规范，这需要一个必须成功管理的结构化框架。RMODP的目的是定义这样一个框架。开放式分布式处理参考模型（RM-ODP）提供了一个框架，在该框架内可以集成对分布、互操作和可移植性的支持。它定义了：一个对象模型，体系结构的概念和体系结构的ODP系统的开发方面的五个观点。其中包括信息观点。由于使用的数据库管理系统（DBMS）在复杂的网络中大大增加，我们有兴趣，在我们的工作中，通过使用三个模式（静态，动态，不变）在给DBMS规范。本文件的结构安排如下。在文献回顾之后，我们将描述在这项工作中被称为数据库管理系统（DBMS）对象模型的概念的子集。在第三部分中，我们将通过描述DBMS对象来对工程语言和DMBS结构感兴趣。最后，我们将提出DBMS工程规范，并建立模型与实例之间的连接。这介绍了我们在这里描述的语义方法的基本形式。
英文摘要：
Distributed systems can be very large and complex. The various considerations that influence their design can result in a substantial specification, which requires a structured framework that has to be managed successfully. The purpose of the RMODP is to define such a framework. The Reference Model for Open Distributed Processing (RM-ODP) provides a framework within which support of distribution, inter-working and portability can be integrated. It defines: an object model, architectural concepts and architecture for the development of ODP systems in terms of five viewpoints. Which include an information viewpoint. Since the usage of Data bases management systems (DBMS) in complex networks is increasing considerably, we are interested, in our work, in giving DBMS specifications through the use of the three schemas (static, dynamic, invariant). The present paper is organized as follows. After a literature review, we will describe then the subset of concepts considered in this work named the database management system (DBMS) object model. In the third section, we will be interested in the engineering language and DMBS structure by describing essentially DBMS objects. Finally, we will present DBMS engineering specifications and makes the connection between models and their instances. This introduces the basic form of the semantic approach we have described here.
