Abstract:
Problem statement: This study described the analysis, design and implementation of the
Questions-Bank system that allows the students of primary, preparatory and secondary schools to take
web-based quizzes and exams, to download course reviews and previous exams. "Questions-Bank",
means that each question has a weight and area of knowledge deals with it.
INTRODUCTION
Introducing Internet at schools has encouraged the
development of new tools and systems within the scope
of education and training. As a result, a new era of
learning and training approaches has emerged, where
new educational models have been developed, students
could learn independently at any time or location,
simply by connecting to the Net along with the
appropriate systems and tools. Teachers, at the same
time, could teach through “on-line” setting and could
schedule lessons and exams without the classical
physical constraints. This electronic learning approach,
also known as e-learning, has opened new horizons in
teaching for both teachers and students[1-4].
Initial UML interaction diagrams: An interaction
diagram demonstrates a certain aspect of a system by
modeling its behavior. It is used to visualize the
collaboration among several objects to complete a
certain task.
Initial static class diagram: An initial class diagram
(also called the domain model) consists of class and
object diagrams. It is a static model that furnishes a
visual representation of the real-world concepts that are
visible to the user not of software components.
Elements of a domain model are classes and the
relationships between them. It is widely used as a
source of inspiration for designing software objects.
System analysis: The analysis phase is the chief phase
in which the system requirements are identified in more
details. The goal of this phase in the system
development is to refine the system goals into defined
functions and operation.
Hardware and software resources: We have used
some software during our system development such as:
Windows XP professional, Windows Server O/S,
Microsoft office Excel, Microsoft Word, SQL Server
database system, MS Visual Studio.Net and Photo
Shop.
System models:
Scenario: A scenario is a specific sequence of actions
and interactions. It is one particular story of using a
system, or one path through the use case. In our system,
we have developed a simple scenario that illustrated the
basic actions in the system.
