Introduction

Recent surveys on MIS (Management Information System) issues show that effective use of the data resource is very important. For example, one survey shows that data resource is the second top critical issue [ Wiederman et.al. 1991]. On the other hand, the design of effective user interfaces to the database systems has not been vigorously pursued. The major interface language is still SQL, a system that was developed almost 20 years ago [ Chamberlain and Boyce 1994] and was found to be very difficult, even for trained users [ Date 1990; Greenblatt and Waxman 1978; Welty 1985].

With the widespread availability of computers and data to not only MIS professionals but also increasingly to end users, data access will expectedly remain an important issue, but with some new twists. To avoid any bottlenecks caused by heavy end-user demand on MIS professionals, it has become imperative to provide general-purpose database interfaces that enable end users to perform reliable database retrieval (and occasionally design) on their own [ Welty and Stemple 1981]. The user interface provides critical ability for how information in a database is absorbed, accessed, and used, because the interface would directly affect the efficiency when users use the database. If the databases are integrated with the Webs, the interface of database must be built on the Webs. But how can we utilize the characteristics, like HTML, Java and JavaScript etc., of webpages for interface design?
