Course Project#1: Agile software development with UML (Unified Modeling Language)

1) I NEED HELP IN CREATING A SYSTEM (ARCHITECTURE) DOCUMENT, TO SOLVE:

**This will translate the SRS Document listed in Posting #256393 into this design document. This will be the technical solution for this project, written from the project's perspective, mainly for the technical people who will be coding and building the system. The design document will include architectural diagram of the project and data models**

1. CASE EXAMPLE: creating an University Registration Information System :

**CASE BACKGROUND**

a.Most schools experience a challenge matching up faculty, courses & classrooms. Some considerations they must keep in mind are making that every courseis offered at least once a year, making certain the right professors are assigned to the right courses, and making certain studetns most in need of courses to graduate get preference. There are many variables to do assignments manually. A simple information system could make this task easy. In addition, by publishing the schedule online, students & professors alike, will know their assignments in advance.

**STATEMENT OF WORK**

a. For a local University design a system that will meet the below requirements:

**SYSTEM REQUIREMENTS**

a. Assign course & professors to classrooms each term

b. Assign students to those course based on priorities given to seniors & those in major tracks

c. Publish class rosters for each classroom

d. Publish a report showing which professors will be assigned where

e. Online Access: Information produced by this system should be accessible online

f. Pre-requisites: Enrollment rights are contingent on completion of course pre-requisites

g. Academic Calendar: The academic calendar starts in the Fall and ends in the Summer

h. Software and Hardware: Evaluate system needs by providing a budget proposal for hardware, software and licensing costs.

Such as for server systems, operating systems and software environments. Suggestions: Enterprise x86 Servers with Microsoft Windows 2008 64-bit Operating systems, Multi-Processors, TCP/IP Networking, IIS7 ASP.Net 3.5 web application environment, Microsoft SQL Server with licenses.

i. Browser: should support Microsoft IE6

j. System Resolution: 1024x680 minimum

k. Probation Status: The automatic registration system must ensure students on probation status aren't allowed to enroll in more than 15 credits per term

l. Delinquent Payment: The automatic registration system must not allow enrollment by students with past due course payments

m. Usage Forecast: Worst case: Professors=75, Students=800-1000. Highest system demand (traffic) = 1 week before & 1 week after each semester starts.

n. Administrative Support: The University currently has 11 registration administrators, covering two staggered shifts. Work schedule is Mon - Fri. The system should be available 24/7.

o. Course Cancellation: System should send automatic email notification to Students and Professors when course is cancelled (i.e. less than 10 students)

p. Staffing: The automatic registration system must have a minimum/maximum enrollment requirement: 10 Students minimum, and 25 Students maximum

q. User requirements: each should be assigned a priority level (high/medium/low)

**ASSUMPTIONS**:

a) A DBMS database management system with student, professor, administrator and course information does currently exist.

b) An accounting system with student payment statuses also currently exists.

c) The system design will use existing data where available, but will add database tables for new system functionality as needed.

d) Currently, the university uses a number of offline tools. None of these offline systems communicates with each other, which means the Registration Administrators use multiple MS Excel files to manage the process. Unfortunately, the biggest problem they have with the files includes no centralized storing, multiple data entry errors, and some incomplete files.

2. Just a note, the format that you produce doesn't have to be in a finished state, I'm more concerned about the developed concepts

3. I also have attached various supporting documents from my course to assist you with the different topics I list below. And I can send additional examples of each of the phases I've described below.

2) Then assistance with creating the software concept:
