Abstract: The methodology and technique tips in designing the EMPRESS database GUI software package are presented. The package is developed for the control system of the large sky area multi-object fiber spectroscopic telescope. A number of advanced techniques are adopted in the design such as dynamic creation of control widgets, dynamic query and share memory. The seamless connection between EMPRESS and the graphical development tool of QNX's PHAB is realized, and so have the Windows look and feel yet under Unix-like operating system. What is more, the package provides the user with a friendly and powerful function of dynamic creation of database tables.
