When analysing an organization’s business processes, there are usually some issues which need to be clarified before you can proceed, particularly when the issues affect the way you developed your models.When developing each diagram, you may make some assumptions which will affect the results of your presented modelling diagram. For example, right after a presented diagram, explain each diagram to your readers and your assumptions made in modelling it.
Assignment 1 Layout and Submission Guidelines
The written assessment - Section 1 should be organised using the following headings and guidelines when preparing your report: o Title Cover Page with clear details of course title/name, student number/name, lecturer name
o Introduction o Identify the aim of the report and the project objectives o The identified problem for the information system project and project approval.

Answer:
Class diagram is composed of four different classes which outlines the interacting entities in The Sports Report Information System (TSRIS). The main class is member which entirely supports all other classes. Without member class, all other classes cannot operate. Assumptions are; president would be able to select required content of the report that suits specific needs. The next assumption is that president would generate report by click of a button with need to write SQL queries.
A use case diagram in this case represents interaction between actors and The Sports Report Information System (TSRIS). All actors should be registered in order to interact with system. The assumptions are; president would register the register all sporting members who are to take part in publication. Similarly, member would be able to perform different activities depending on privileges granted.
- Use case scenarios
|
Use Case ID |
Primary Actor |
Use Cases |
|
President |
Yes |
Login, register member, Register sport, get report |
|
Member |
Yes |
Login, publish and edit newsletter |
The flow of data presented in this case would be specific depending on the user using the system. After login, the user would select the relevant module and execute required duties. In this case, member would be able to login, publish newsletter and edit depending on privileges granted by the president. Assumptions are; database would be in atomic state to facilitate smooth information search.
The interaction between two actors and the system are guided by role they play. Member writes content for publication and submits it to the system for consideration. In return, writer is compensated on all publications made for sporting activities. President can view all publications and members contributions as well make decision based publications available. Assumptions are; president would make decision based on publications made and feedback from several reviews from readers.
Activity
The flow of information is sequential in nature from session created during login to exit of the system. The assumptions are; all articles must be presented for consideration. The next assumption is that, unless user has been registered and granted privileges, publication cannot be done. The final assumption is on error checking, once an article has errors, it should not be allowed to proceed to the next stage of publication.
ASC Interfaces
The design of any information system interface should be guided by design principles. These principles are; simple interface, ease of accessing menus and location of buttons. Assumptions are; there should be approvals before some publications can be done. The other assumption is that, ASC system would be online for ease of access from anywhere.
