April, 2001 Computer Science Design and Implementation of a Web Server Application for Students to Submit Assignments Chairperson: Alden Wright This project is a software engineering approach to the design and implementation of a web server application for students to submit assignments. During the design and analysis of the project, a requirements document, high-level use cases and expended use cases documents, class diagrams and sequence diagrams have been finished. The project uses Java servlet programming to implement the application system. There are two parts in the application system, an instructor part and a student part. For an instructor user, the system allows the instructor to set up a course for students to submit their assignments. The system allows the instructor to set up and to modify the assignment size limitation, to edit the course and student passwords, to check student submission information online, and to delete a student account. The system also allows the instructor to delete his/her course account. For a student user, the system allows each student to set up a password-protected account for assignment Submission. Students can submit their assignments online after they set up their account. The system also allows students to edit their passwords. A web demo of the project has been set up. All of the functionalities in the application work. The design and implementation of the project is summarized in the paper. Some questions and experiences with the design and implementation of the project are also discussed in the paper. A recommendation for future work has been suggested. From this project, I learned a lot of software engineering methodology, from requirements analysis, to elicitation of use cases, to architecture and detail design of the project, to extraction of sequence diagrams and class diagrams. Through the project, I increased the abilities of solving technical problems, which were not familiar areas to me. All of these experiences are very helpful for me to continue to work in the J2EE area. Acknowledgment I would like to thank my advisor Dr. Alden Wright for his assistance, support and encouragement. I would also like to thank Dr. Joel Henry and Dr. Lee Tangedahl for their helpful suggestions. Contents 1.

Introduction The Internet and the World Wide Web have experienced explosive growth over the past decade and are now positioned to provide a wide range of services. Computers have become and will continue to be part of our everyday lives. More and more individuals, organization and business use networks to get and send information. Generally, when a student takes a course in a university, he /she has to finish the required assignments and to submit them to the instructor. In computer-related courses, assignments are often submitted electronically in the form of computer files. Traditionally, when a student wants to submit an assignment electronically, he/she has turn in a floppy disk, to send the file to the instructor by email dr to copy the file to a course directory, which has been set up for that purpose. However, there are four major problems with these methods of submitting assignments: (1) If the floppy disk submission method is used, the instructor has to retrieve the assignment from one floppy disk per student, which will take the instructor a lot of time because the machine reads a file from a floppy disk much slower than from a hard disk. Also, both students and the instructor have to use the same format system to write and read a floppy disk. (2) If the email submission method is used, the instructor has to deal with a large number of email messages, which contain student assignment files. It is not surprising that the instructor may receive more than one hundred emails in a 50-student course for an assignment. A student may send several modified assignment files for an assignment. The instructor has to save these files to a directory and verify and delete duplicate submissions. (3) If the copy-file submission method is used, the student must have an account on the machine where the instructor asks students to copy their files to a course directory. The students can go to the course directory and view other students file information, such as who have submitted their files and when the files have been submitted. Because of this security

In the use. workshop, attendees will modify an existing report and display the results in various web based formats, including HTML, PDF Three components are required for the SAS/INTRNET software and RTF. to work. INTRODUCTION 1) Web Server Software – such as Microsoft’s Personal To do this, we’ll use Dreamweaver software as a GUI tool to Web Server/Internet Information Services, or the create HTML web pages. We’ll use SAS/Intrnet software as a Apache Web Server. back end tool to execute SAS programs with parameters selected on the HTML screen presented to the user. 2) Web Browser – Such as Microsoft’s Internet Explorer or Netscape’s Navigator. Our goal is to create the following screen for user input. 3) SAS/INTRNET Software – Called the Application Dispatcher. It is composed of 2 pieces. o SAS Application Server – A SAS program on a Server licensed with the SAS/INTRNET Module. o Application Broker – A Common Gateway Interface (CGI) program that resides on the web server and communicates between the Browser and the Application Server. These components can all reside on the same system, or on different systems. Types of Services 1) Socket Service: is constantly running, waiting for incoming Transactions.

  • Fiz: a Component Framework for Web Applications
    Fiz: A Component Framework for Web Applications John K. Ousterhout Department of Computer Science Stanford University Abstract Fiz is a framework for developing interactive Web applications. Its overall goal is to raise the level of programming for Web applications, first by providing a set of high-level reusable components that simplify the task of creating interactive Web applications, and second by providing a framework that encourages other people to create addi- tional components. Components in Fiz cover both the front-end of Web applications (managing a browser-based user interface) and the back end (managing the application's data). Fiz makes it possible to create components that encapsulate complex behaviors such as Ajax-based updates, hiding many of the Web's complexities from applica- tion developers. Because of its focus on components, Fiz does not use mechanisms such as templates and model- view-controller in the same way as other frameworks. ger and more useful structures.
