MOSS Current SIU Problem Believe it or not, there are some CS students at SIU that do NOT code their own programming assignments. Instructors need a way to check multiple programming assignments for similarity. Doing this by hand takes way too long. There exists an application hosted by U.C. at Berkeley called MOSS (Measure Of Software Similarity) that compares programs, but currently, the process of requesting MOSS services is not convenient.

MOSS Current MOSS Problems Command line interface to run a Perl script for UNIX. Not integrated with SIU student drop boxes. No GUI or MOSS I/O automation. 2 week lifetime of MOSS reports. No locality of MOSS reports.

MOSS Requirements Analysis

MOSS Requirements Analysis Client interview sessions. Perl script analysis and functional decomposition. Prototype of MOSS service requests. Subsequent review of MOSS reports. Constant review with client.

MOSS View Results within 14 days Current View of MOSS Reports

MOSS RISK Create attachments from file groups made from user selections. Automatically send MOSS requests via with attachments. Automatically retrieve, open, and parse MOSS reports. Automatically web tunnel into MOSS reports URL. Automatically store MOSS reports to local web page. MOSS Risk Mitigation Items

MOSS Our Solution The Code Cop System requirements: Easy to use GUI. Automated MOSS I/O. Integrate student drop boxes into the system. Integrate with instructor class spreadsheets. Thin client / 100% Web hosted functionality. Local archive of MOSS reports.

MOSS Development Platform Windows 2000 because: Client requirements. Our groups programming skill set. Readily available development tools. SIU Web pages are hosted on MS IIS.

MOSS Functional Requirements Instructors: Can create, edit, or delete courses. Can add, edit, or delete students from courses. Can switch students between sections. Can bundle MOSS requests from multiple sections. Can specify base files to be sent to MOSS. Local archive of MOSS reports. MOSS reports posted to Web site. Student uploads are filename constrained. Set homework deadline.

MOSS Functional Requirements Administrator: Can add, edit, or delete users. Can add, edit, or delete courses. Student: Can submit their programs via a Web interface. Can view the status of their directory.

MOSS Project Plan

MOSS Hardware/Languages 1.Hardware Decisions: Windows 2000 dedicated server 2.Languages: ASP, HTML, SQL, Visual Basic, Java

MOSS Implementation Requirements Resources: Code Cop will require space on the CSFS2 server. Must have Internet access. Requires an account to send/receive info. Microsoft Access database. Microsoft Internet Information Server.

MOSS Development Tools / Software Microsoft Visual Studio 6.0 Enterprise Edition Third Party Components: ASPMail 4.0 – used for sending messages using SMTP JMail – used for receiving messages using POP3

MOSS Test Plan The Lead Tester is responsible for developing a system of testing which includes: Lo-fi and Hi-fi prototyping at the early stages of development. Making sure that all features agreed upon are in the application. Debugging and Testing of all Routines.

MOSS Test Plan (cont.) Documentation will include: Why the test is being conducted How the test will be conducted Where the test will be conducted When the test will be conducted Who will conduct the test Every test will be documented

MOSS Deployment Plan Installation on CS Dept. Windows 2000 Server Entire CodeCop application will be in one place Training Client and other instructors will need to learn the UI Student Web Interface (optional per Instructor)

MOSS Deployment Plan (cont.) Operation (continued) CodeCop System will need very little maintenance Requires server to be up and running Requires server to maintain a connection to network
