Abstract

The user interface is a critical portion of any application program. Many EM databases reside in dBASE ™, relational database management systems (RDBMS). The user interface for dBASE ™ RDBMS consists of menu choices and templates for the display of database fields. User interaction with menus and templates is by sequential keyboard input. Though the dBASE ™ RDBMS provides excellent support for database functions there is little support for the design of a functional user interface. Menus of screen choices, templates for field display and the requirement for keyboard input tend to overwhelm all but the most experienced computer user. Since most users prefer screen displays which include familiar objects, any improvement in the user interface for EM databases should seek to simulate these objects in the user interface. Because HyperPAD ™ allows the simulation of familiar objects during screen design, it is an excellent tool for constructing an improved user interface for EM databases in dBASE ™ file format.
