Interoperability in Heterogeneous Database System: A Workshop, Boulder, Colorado, February 10-12, 1992

研讨会探讨了互操作数据和知识库的应用和研究问题。多数据库互操作性和语义异构的解决构成了开发需要访问多个信息资源的复杂应用程序的支持技术。主要目的是将工业界和学术界的研究人员聚集在一起，讨论基础研究如何解决应用程序在异构数据库环境中遇到的问题。参加者有机会研究业界代表提出的实际用户问题。基础研究人员和应用研究人员之间的合作可以建立在基础研究创造的坚实基础之上。主要讨论的主题包括：来自不同来源的信息的语义集成；解决语义不兼容的方法；多数据库环境下的查询优化技术与分布式事务处理异步数据处理的描述性建模；并将新兴技术（如活动和面向对象的数据库）合并到多数据库系统中。预期讲习班的结果将在稍后出版的最后报告中加以总结。该报告将评估在多数据库互操作性方面取得的进展，并确定需要进一步研究的领域。

The workshop investigates application and research issues of interoperating data and knowledge bases. Multidatabase interoperability and resolution of semantic heterogeneity constitute enabling technologies for the development of complex applications requiring access to multiple information resources. The main objective is to bring together researchers from industry and academia to discuss how the basic research addresses problems encountered by applications in the heterogeneous database environment. Participants have an opportunity to study real user problems identified by the industry representatives. The collaboration between basic and application researchers can then be based on a solid foundation created by basic research. The main topics to be discussed include: semantic integration of information from diverse sources; methods to resolve semantic incompatibilities; query optimization techniques and distributed transaction processing in multidatabase environments; descriptive modeling of asynchronous data processing; and incorporation of emerging technologies (such as active and object-oriented databases) into multidatabase systems. It is expected that the results of the workshop will be summarized in a final report to be published later. The report will evaluate the progress made in multidatabase interoperability and identify areas in need of further research.
