.: About The Project :..: About The Project :.
The software Jabberwocky is a quizzing management software which is suited for a wide range of users – end users wanting to participate in quizzes, quizmasters who want a quizzing software during stage events, and quiz database administrators who want an easy way to manage large databases. To achieve this, the program offers the following user modes, with different feature sets:
➔ Normal User Mode: Anyone can use this mode, which allows a user to attempt questions in the included database. Questions are presented in a multiple-choice format, with automatic scoring. After the user chooses to exit the session, he / she is presented with extended statistics about his / her quizzing session.
➔ Administrator Mode: An authenticated mode, it allows the user to carry out advanced functions like managing question and / or user database, accessing overall statistics about all users, searching users by different criteria, and changing current administration password. It also offers a Quizmaster Mode, intended to be stage-round specific mode for a quiz, which allows the authenticated user to view the correct answer along with the questions and their options.
Jabberwocky – The Quizzing Software also provides a help file accessible providing introductory information to users about its different features. Users have the option to use any one of the two versions of the program – a text-mode version, and a graphics-mode version dependent on the Borland Graphics Library. Both the versions are bundled with a demo question and user database, and also with the necessary graphics libraries for the graphics-mode version.
