Introduction

The purpose of this document is to describe the planned user interface for the Stateless University Registration System. It will be revised to reflect that "as-built" software after system testing has begun. It is a customized version of the registration system delivered to Universal Online University (UOU) last year. Stateless U has requested some major modifications to the UOU version, so that it is essentially a rewrite of the software. Some of the modules for database creation and backup have been reused, but that is not apparent from the user interface, which is all new.

This manual has the user interface screens defined in the order in which they are customarily used. It starts with the login screen. Then it provides the data base set-up fields: the addition / change / deletion of students, the addition / change / deletion of courses, and the addition / change / deletion of class sections. The final data entry screen provides the selection of specific course sections for each student. There is also an administrative function that is accessible to only the supervisor. It provides access to the administrative functions of backup and restore of the databases. Each screen is defined in a separate section providing the following information:

The figure below summarizes the screens and their navigation options.
