3 1. INTRODUCTION This project is focusing on implementing a web-based application for Student Textbook Exchange System which simplifies the way of buying and selling textbook online among the students at King Saud University. The application will manage the communication between King Saud University students according to predefined requirements as this Web-based application is considered a good strategy to help students find their needed textbooks. There are different types of users as sellers and/or buyers. The seller is a person who can upload the academic textbooks who is willing to sell them and get benefit of the process, while the buyers are those who are willing to search and purchase the required text book at the specified price. However, both seller and buyer should register in the system before conducting any process of the application. The registration will require the first and last name of the student, address, and password. The features of this application will allow the seller to add a brief description about the text book, ISBN, authors, and the main categories. Moreover, the seller could receive a reminder via his automatically from the system when there is intent to purchase from another user (i.e. the buyer). Also, the system will remove the sold textbook from the system once the purchasing process is completed. Page 3

4 Finally, we do believe that this application will add value to the community of our university and save their time, cost and efforts. The document include describe the users for the system through a user characteristics. Additionally, the project scope such as Project In-scope and out-scope. Also, In Requirements Determination to find our features will do comparing with similar systems Literature Review, stakeholder interviews and questioner. The document will also include the specific requirements needed that determine the different software services and considerations required. These will contain the user and system requirements and the system's functional and non-functional requirements. To explain the systems functions and task by more easily and flexibility, the document will include use cases with diagram that s showing the system model which reflects the overall system processes of different relationships and tasks. Finally, Readers could refer to the table of contents if searching for something in specific way, Also references and appendices which include any graphs or content. Page 4
