After interview with a customer, System analyst write a detailed ruff report of system specification that is provided to you below;
System RequirementsTour de Pakistan (TdP) is a private limited company, offering a variety of tours within Pakistan which are highly in demand along with newly entertaining visiting spots as well and hence most of their customers book their tours well in advance.
During each tour, the customers / travelers will be visiting many sites. All those sites offer site seeing, however only some of those sites offer various activities in which the visitors / customers can participate. Some of the sites that are visited in a tour may also be included in other tours. For each of the tours, a tour guide is allotted by TdP.
Each tour must have a distinct name containing sites and activities (if available on those sites) and fixed no of seats. So, few sites in tour may be with activities while other are without activities. Sites with or without activities are not fixed and totally depends on company’s owners tat design the tour as per customer’s demand / visitor’s trends. Only one tour guide is allocated for one tour. Prices for tours are fixed and payments are done by visiting their office or deposited online if tours are reserved online.
The web page should have necessary controls and easy to understand layout that are necessary to receive the input data and the application should store them appropriately. The web page’s layout is left to developer’s choice, but it must be simple, attractive and understandable. The page should also be user-friendly and is expected to display appropriate error/warning messages. The data type for each of the inputs has not been mentioned purposely. You need to use appropriate data type accordingly.
Only owners / administration will create / authenticate tour guide’s login. Administration has responsibilities to create tours, sites and activities while owners would also have authority to enter / edit / create tours with limited / fixed seats. Plans are viewed by travelers and then book number of seats against each tour and payments are done by using credit card. Visitor / traveler is not allowed by system to book two different tours which start or end dates are overlapped. Visitor / traveler may apply for cancelation of tour plan and concerned administration and owner only allowed to cancel that tour reservation before one week of start date.
TASK to perform
You must identify following from the project specification / requirements that are written by System analyst after interview with customer;
1 - User Characteristics or type of users [10 Marks]
2 - Functional Requirements (at least 5) [10 Marks]Best of Luck!

After interview with a customer, System analyst write a report of system specification that is provided to you below;
Scenario / System Requirements
The aim of this project is to develop a website named as “University Certificate Management” to provide instant updates about the status of an application in a University. Using this web-based application, students can submit their applications to the relevant department and then track the progress of their applications. Verifier can login to the system and check the certificates given by University are valid or not. The users of this website are Admin, Students, Teachers, Examination Clerical Staff, Finance staff and from outside Verifier.
The system will store the below information in it.
• Student basic Details
• Semester and Course Details
• Certificate Templates
• Events/Functions Details
• Staff DetailsTo use the system, user must be register with the system. The system admin have to approve user registration request. Only Clerical Staff and Teachers are allowed to insert the data. Students can only view the details and apply for the required certificate. Verifier can only check certificate authenticity. Only admin has right to see / alter some basic information of users e.g. in case of password lost, admin would help user to recover / reset system password.
Major properties that system should have:
Following are the key functional requirements of proposed Project:
• Sign In and User Registration
There will be two categories of users:
• Internal Users (Admin, Students, Teachers, Examination Clerical Staff, Finance staff)
• External Users (Verifier)Clerical Staff will have the privileges to upload students and teachers information on the website.
Admin will be the user of website having rights of user management. Admin will approve the registration requests from users and recover accounts for registered users.
There will be Sign In interface for registered users and Sign Up interface for unregistered users to register on the website.• Information Uploading / Posting
• Examination Clerks are responsible for Semester and course related data management and assign courses to Teachers.
• Teachers are responsible for the grades and the assessment related data of their students.
• Finance Clerks are responsible of Fee related data management.• Information Retrieval:
• Students can check their pass courses and request for certificates.
• External Users can only verify the certificates after authentication.• Generating Certificates
• A verification interface must present to check whether request is valid or not.
• Examination Clerks create certificate on user request after proper verification.Tasks to Perform
You have to identify following from the project specification / requirements that are written by System analyst after interview with customer;
1 - User Characteristics or type of users [5 Marks]
2 - Functional Requirements (at least 5) [10 Marks]Best of Luck!

Assignment 2
TASK to performIn continuation of assignment 1 of CS312, by using system requirements, we identified following entities in the system under observation;
- Admin / Owner
- Tour Plan
- Sites
- Activity
- Visitor
- Guide
By considering these entities in your system, you must identify entity attributes and cardinality between provided entities. Note that you are not required to add any extra entity from your side that would result in deduction of marks. So, your Task is to;
TASK: [Marks = 10 + 10 = 20]
Draw ER diagram containing entities, assumed attributes and cardinalities between these entities.
(If you have any assumptions regarding system then also specify these in your solution.)
