Abstract

Currently, there exists two different methods for database retrieval in the internet. First is to use the search engine and the second is to use the plug-in or ActiveX technology. If a search engine, which makes use of indices built from keywords of simple text data in order to do a search, is used when accessing a database, first it is not possible to access more than one database at a time, second it is also not possible to support various conditional retrievals as in using query language, and third the set of data received might include may unwanted dta, in other words, precision rate might be relatively low. Plug-in or ActiveX technology make use of Web browser to execute client's query in order to do a database retrieval. Problems associated with this is that it is not possible to activate more than one DBMS simultaneously even if they are of the same data model, second it is not possible to execute a user query other than the ones that are previously defined by the client program. In this paper, to resolve those aforementioned problems, we design and implement database retrieval system using a virtual database, which makes it possible to provide direct query interface through the conventional Web browser. We assume that the virtual database is designed and aggregated from more than one relational database using the same data model.
