Flex: a Modular Software Architecture for Flight License Exam

Abstract

This paper is about the design and implementation of an examination system based on World Wide Web. It is called FLEX-Flight License Exam Software. We designed and implemented flexible and modular software architecture. The implemented system has basic specifications such as appending questions in system building exams with these appended questions and making students to take these exams. There are three different types of users with different authorizations. These are system administrator operators and students. System administrator operates and maintains the system and also audits the system integrity. The system administrator can not be able to change the result of exams and can not take an exam. Operator module includes instructors. Operators have some privileges such as preparing exams entering questions changing the existing questions and etc. Students can log on the system and can be accessed to exams by a certain URL. The other characteristic of our system is that operators and system administrator are not able to delete questions due to the security problems. Exam questions can be inserted on their topics and lectures in the database. Thusoperators and system administrator can easily choose questions. When all these are taken into consideration FLEX software provides opportunities to many students to take exams at the same time in safe reliable and user friendly conditions. It is also reliable examination system for the authorized aviation administration companies. Web development platform - LAMPLinux Apache web server MySQL Object-oriented scripting Language - PHP are used for developing the system and page structures are developed by Content Management System - CMS.
