数据类型鉴别器在CORBA分布式异构系统中的应用

Use of Data Type Discriminator in Realizing General Query Database for CORBA Distributed Heterogeneous System

分布式异构系统中的数据类型转换 ,一直是计算机、自动化领域内人们关心的重要问题 .CORBA应用于电力系统 ,处理异构系统的数据类型转换 ,在国内尚无成功的经验 .本文提出将CORBA应用在电力系统并提出了数据类型鉴别器的概念 ,较好地解决了某电力控制中心的分布式异构系统中数据库的通用查询问题 。

Data type conversion in distributed heterogeneous system is all along an important problem related to the computer and automatic domain. In electric power system, there wasn't any successful application that use CORBA in such a conversion in our country. This paper presents that CORBA can be used in electric power system, and further, it presents a new concept of data type discriminator. These two ideas above are feasible with the solution of the problem of a general query about the database in a distributed heterogeneous system of an electric control center.
