摘要

多数据库系统(MDBS)最重要的特点是提供集成各种本地数据库系统(LDBS)模型的全局模式。然而，由于ldbms的语法和语义表达的差异，使得局部模式难以集成到全局模式中。本文提出了一种标准的SQL扩展，称为多数据库查询语言(MQL)。此外，我们还使用案例研究分析了语义冲突，并使用MQL提供了语义冲突的解决方案。

SQL Extension for Multidatabase System

The most important feature of a multidatabase system (MDBS) is to provide the global schema with integrating various models of local database systems (LDBS). However, it is difficult to integrate local schemas into the global schema due to the difference of the syntactical and semantic expressions of LDBSs. In this paper, we propose the standard SQL extension for MDBS called by Multidatabase Query Language (MQL). In addition, we analyze semantic conflicts using case studies and provide solutions to the semantic conflicts using MQL.
