Assignment: System Analysis and Design

The Association for Information Systems would like to make an online application for tracking undergraduate, graduate, and PhD academic programs in universities around the world. You have been hired as a consultant to redesign the system that will be capable of the tasks described below. Use diagramming tools covered in class to provide a description of the system: use case diagram, class diagram, and either activity diagram or sequence diagram, whichever you find more useful.

The web application is reached via a URL and works as a standard web page accessible to all browsers. It is a back-end application with an html user interface, and data is stored in a database.

Users can pull up a starting page where they have a choice to either view program listings, submit a new listing or to modify their submission if they submitted a listing to the system previously. To view listings, users may filter the listings by type of program (undergrad, grad, PhD) and country (Fig. 1), after which they click on a button and listings are presented in a tabular format (Fig 2). From there users can make a new search, edit their listing or submit a new one.

To modify their submissions, users need to log in (Fig 3) and after successful authentication, they are presented with a list of submitted programs (Fig 4). They choose an entry from the list and are taken to a form filled in with previously submitted values (Fig 5). Users can edit this form and resubmit, they can delete the record, or they can cancel any changes. When cancelling, the system will log them out and send them to the starting page. Users can also change their login information (username,password) on a page that checks the new credentials (typed twice) or they can cancel the change (Fig 6).

To submit a new program, users fill out a detailed form about the program, as well as their contact and login information, which is later used to log them into the system for modifications (Fig 7).

The information collected about programs is almost the same regardless of type. However, PhD programs have additional data (Fig 8) and there should be an option in the future to also collect more information about the graduate programs when compared to the undergraduate.

To prevent abuse, and to monitor the content of the IS program database, the newly entered programs are stored in a temporary database called Pending submissions. From there they are moved by editors who are assigned to oversee the submissions to an approved storage called Live database.

There are many editors who are in charge of overseeing the submissions by users. Editors are identified by username and password, and are given a domain of responsibility which is either undergraduate, graduate, or PhD.

Editors can log into the system (Fig 9) and view both databases, Pending and Live (Fig 10). Both databases can be sorted by program id, university name and country in both ascending and descending order. The listings can be selected and deselected individually, or all/none, so that operations can be performed on the selected set.

Each record can be viewed individually, that is, all of the submission details are shown (Fig 11). They can be viewed as a selected set; then only a summary of the detail is shown (Fig 12).

The records can be modified and updated individually (Fig 13). The records can also be deleted in group or one by one.
In addition to these operations, for Pending submissions, records can be selected and "Approved", i.e., they are moved from the

Pending to Live databases.

In addition to performing these database operations, the editors can also change their username and password information. They can also logout and login with different credentials, to facilitate one person acting as multiple editors for different program domains.
