1.0 GENERAL INFORMATION
1.1 System Overview
The Project Group Assignment System (hereby referred to as the "System") is a Web-based application developed on client/server architecture to automate the process of assigning groups to projects for the CS 631X, CS 615 and CS 616 Software Engineering Seminar courses. These courses and especially the Software Engineering Seminar, which is spread over 2 semesters, have clients who provide projects , and students that are distributed in various teams. These 4 entities form the base for the System, with its primary intention being to automate the creation, management and administration of these entities, with core focus on assignment of teams to projects.
The System is designed as a single point interface to administer the activities and attributes of the 4 primary entities, based on the user role and access permissions. The interface is a simple to use Graphical User Interface (GUI) displayed on a web browser. No former technical knowledge is needed to operate and use the System. The text, graphics, layout and flow of information and process are intuitive, and guide the user through the System. The Administrator is expected to have more knowledge of the principles and processes that guide this System, rather than the technicalities involved.
The System, based on Client/Server architecture, uses a thin-client (web browser) as the client, which makes it extremely fast and simple to use. Any web browser is capable of serving as the client, onto which the GUI is displayed. The preferred browser is Microsoft Internet Explorer 5.0 and above, though the System has similar functionality and appearance on Netscape Navigator 6.0 and above, and other browsers.

2.0 SYSTEM SUMMARY
The System, as briefly described above is based on Client/Server Architecture, with a web browser serving as the most commonly used client. The server is maintained at the CSIS Department at Pace University, and Dr.Charles Tappert can be contacted regarding the current Server Administrator in case of server-related issues. These issues / topics are beyond the scope of this document.
Cold Fusion is the primary technology used for Client – Server communication, while extensive SQL and PL/SQL are used in the SQL Server based back-end for data retrieval and querying. HTML is the markup language with JavaScript as the client scripting language. The usage of these technologies makes the system robust, scalable and flexible to various client configurations.
2.1 System Configuration
Web-browsers like Internet Explorer and Netscape Navigator are the most commonly used clients, hence making their configuration independent of the System. The System is not dependant on personalized browser settings, and functions equally well on all browsers. Personalized settings such as client script enabling, setting of cookies etc have no impact on the System’s functioning.
In order to access the System, the minimal requirements are –
1. Windows 2000 and above / Linux / Unix based machine.2. 64 MB RAM.3. Web-Browser such as Microsoft’s Internet Explorer (Preferred), Netscape’s
Navigator or Communicator, Opera etc.4. Configured LAN / At least 56 kbps internet line / DSL / Cable / Other ISP.
No other plug-ins, third party tools, installations or Virtual Machines (VMs) are required to access the system.

Appendix 1 : Database Schema and Access
The System Database is located at http://utopia.csis.pace.edu/ and can be accessed via http://utopia.csis.pace.edu/phpmyadmin/. PHP MyAdmin provides the User Interface to access the database, and make changes to its schema and data. MyAdmin is a intuitive, easy-to-use interface that encapsulates the complexities of the database schema and SQL from the user. Currently, no username and password are required to gain access to the database.
On visiting http://utopia.csis.pace.edu/phpmyadmin/, the following screen comes up -
Fig 1 – PHPMyAdmin Welcome screen
From this screen, scroll down on the left pane that displays various databases to the database named “Team13”. This is the database for the System, and is illustrated in the following screen -
35
Fig 2 – Team 13 Database – Back-end for the System
The database consists of 12 tables listed below –
tblChoices – Holds the choices entered by the user for the survey. tblClient – Holds client details. tblCourse – Holds course related details. tblExperience – Holds experience details which are used in the survey. tblLocation - Holds location details which are used in the survey. tblParameters – Holds the names of parameters and their weight age to be used by the
algorithm. tblProjects – Holds project details. tblResults – Holds results of the algorithm runs. tblSemester – Holds names of semesters, associated courses and the year. tblState – Holds State names, also used in the survey tblTime – Holds Time Slots, used in the survey tblUser – Holds User details.
A Note about all tables – In order for the System to function normally, please leave at least 1 entry (1 row) in each table. This ensures no errors are generated while using the System.The following is a detailed description of what each table contains, and details on how to change / add data in these tables, and also explanation of their impact.
1. Table tblChoices
36
This table contains the actual choices entered by the user while taking the Student Survey. It contains a mapping of all their selected choices and their respective values. Here is the schema for this table –
Fig 3 – TblChoices Schema
The following is a data snap shot of this table –
Fig 4 – TblChoices Sample Data2. Table tblClient
37
This table houses the client details. When an administrator chooses to create a new client, all information pertinent to that client is stored in this table. The following are the schema and data shots of this table –
Fig 5 – tblClient Schema
Fig 6 – tblClient Data
3.Table tblCourse
38
This table holds Course and Semester Information. This information is used while adding a particular project to a course. Hence, to add new courses / semesters into the System, Insert a Row into this table with the relevant course, semester and year details. Here are the schema and data shots for this table -
Fig 7 – tblCourse Schema
39
Fig 8 – tblCourse Data
4. Table tblExperience
This table holds Experience information, which is used in the survey. If any further experience related information needs to be added to the survey, add the information to this table, and it will be reflected in the survey. Here are the schema and data shots -
40
Fig 9 – tblExperience Schema
Fig 10 – tblExperience Data
41
5. Table tblLocation
This table houses all the Location options provided to the user during the survey. If any more locations need to be added, or modified, this is the table to make changes in. Following are the schema and data shots -
Fig 11 – TblLocation Schema
Fig 12 – TblLocation Data
42
6. Table tblParameters
This table houses all the Parameters, and their weight age, which is internally used in the algorithm. This is the core table from the algorithm point of view. Any change to the algorithm might require a corresponding change to the data or possibly the schema of this table. For example, if the weight age structure needs to be re-organized, or another parameter needs to be introduced into the algorithm, this is the table that would require the change.
Following are the schema and data shots –
Fig 13 – TblParameters Schema
43
Fig 14 – TblParameters Data
7. Table tblProject
This table houses all the Project-related information. Any new project added is entered internally into this database. Any changes to the way projects are entered / associated need to be reflected in this table. Following are the schema and data shots -
Fig 14 – TblProject Schema
44
Fig 15 – TblProject Data
8. Table tblResults
This table contains the results of the algorithm runs – in a nutshell, the algorithm uses the various parameters from the tblParameters table, runs the code, and associates Users to particular Projects and Courses and stores them in this table. Following are the screen shots for this table -
Fig 16 – TblResults Schema
45
Fig 17 – TblResults Data
9. Table TblSemester
This table is not currently being used, and DOES NOT contain any data.
Fig 18 – TblSemester Schema
46
10. Table TblState
This table contains a list of states, also used during the student survey. To add / modify / remove a state, this is the table to be changed.

11. Table TblTime
This table holds the time slots used during the Student Survey. If new time slots need to be added / modified / removed, this is the table to do so in.
Fig 21 – TblTime Schema
48
Fig 22 – TblTime Data
12. Table TblUser
This table contains all the user details when an administrator creates a new user (Student). This table is one of the key tables in the database, and if any more information needs to be stored about the users, changes need to be made to the schema of this table.

Conclusion
The System is now configured to run for any Semester from Spring 2002 until Spring 2005 for the CS 615 and 616 courses under Dr.Charles Tappert. Any further courses / semesters can be added using the guidelines in this document. Application Code has been modified to accept these additions / modifications in the database schema as well.
Suggested Future Enhancements
1. The System can be tweaked to perform more efficiently in terms of the internal algorithm. The weight age mechanism can be revised, and more parameters can be added to the algorithm to better match student requirements.
2. A report page (rptChoices.cfm or similar) showing the details of all preferences of all students can be added to the System, and a sub-section (View Preferences) can be added at the Administrator Home Page. This will better assist the instructors to view student preferences from the User Interface itself.
3. The System may be migrated from Cold Fusion to Java, .NET or a more relevant and later technology architecture.
More enhancements / suggestions will be added as the System is used progressively in time.
