3、es). Also, archival storage of databases relies on the lecturer for the current semester not removing or overwrit- ing the snapshot databases from earlier semesters.A second problem is that there is no useful integration

4、 between the web sites and the SMS/Give systems. If data from SMS needs to be published on the web, it must be manually transferred to the web site. Transfer from the web sites to SMS/Give is not an issue because the web

5、 sites are largely read-only (i.e. they do not collect any data that needs to be uploaded to the SMS/Give system).A third problem relates to lack of accessibility of the systems from outside the UNSW campus. While the co

6、urse web sites are obviously accessible off-campus, the SMS/Give systems are implemented using Tcl/Tk/X- windows and it is not feasible to use them over standard mo- dem connections. This has caused a major inconvenience

7、 to lecturers and students (e.g. students could not check their marks for the course from home).Even when used on the UNSW campus, the SMS/Give systems suffer from some less than satisfactory usability. The systems requi

8、re considerable manual effort to achieve many apparently simple tasks (e.g. generating reports is a tedious process). A particular usability problem is that parts of the system (e.g. the marks finalisation) are used only

9、 once every semester and people readily forget the finer details of using the system from one semester to the next, resulting in considerable frustration.In order to address the above problems, this project pro- poses to

10、 use a a database-backed course management sys- tem using the web as the interface medium. The use of a central database to manage information for all courses solves the consistency and archiving problems mentioned above

11、. The use of a web front-end solves the problem of off-campus accessibility, and, if properly done, can also ad- dress the usability problems. While the discussion here fo- cuses on the application of the system in CSE,

12、the system has been designed with flexibility in mind and should be portable to other educational contexts.An obvious question arises at this point: Systems such as BlackBoard [10] and WebCT[9] already exist and provide

13、much of the functionality described above. So why not sim- ply use them? WebCT and Blackboard are both commercial products, and thus expensive. WebCT is implemented in Perl/CGI and, until recently, did not use a database

14、 back- end. Prometheus [5] is a free, open-source system, but is implemented on top of ColdFusion which is commercial.We were interested in building our own system for sev- eral reasons:? to examine another point in the

15、space of possible im- plementation platforms (Apache/PHP/mSQL)? to see how much effort was involved in building a sys- tem like these? to examine the benefits of developing a purpose-built system over simply using a gene
