Implementing a user interface management system for existing applications using an object‐oriented database tool

Abstract

AbstractNumerous engineering application systems have been developed over the past twenty years, and many of these applications will continue to be used for many years to come. Examples of such applications include CAD Systems, finite‐element analysis packages and inspection systems. Because many of these applications were developed before graphical workstations became available, they often have simple command‐line user interfaces. Thus, there is a need for a graphical user interface management system (UIMS) that can be used to build point‐and‐click style interfaces for these existing engineering applications.In this paper we describe such a UIMS, and discuss its implementation using an object‐oriented database tool. This UIMS allows users to create and modify user interfaces by editing graphical representations of the interfaces, thus eliminating the need to write code to build or modify an interface. The UIMS is implemented using an object‐oriented database tool to take advantage of the data manipulation and storage management capabilities it provides. This approach reduces both the quantity and complexity of the code needed to implement the UIMS. It also allowed the UIMS to be implemented in a minimal amount of time.
