摘要
Diversity and evolution in database applications often result in multidatabase environment in which corporate data are stored in multiple, distributed data source. It is a formidable work to formulate query to access those multidatabase, especially when some complex constraints are involved This article presents MQDP (Multidatabase Query Design and Processing), a graphical user interface to multidatabase. This tool allows user to handle the overwhelming information from different data sources. It has supplied common interface to multidatabase and implemented the multidatabase query optimization in query processing. It has wrapped the heterogeneity of the data and put a uniform manner to the user. In this paper we discuss critical issues of this graphical user interface development for multidatabase.
