MIS605 Systems Analysis and Design - Laureate International Universities

Design specification

Learning Outcome 1: Identify, critically evaluate and recommend information systems solutions for inefficiencies in business processes, procedures and work practices using data and process modelling techniques.

Learning Outcome 2: Formulate, validate and document business requirements for a medium-scale information system development project and effectively communicate these requirements to the stakeholders.

Learning Outcome 3: Demonstrate the ability to effectively analyse, design and develop information systems using Unified Modelling Language (UML) models.

Instructions

1. Please read MIS605_Assessment 1_Case Study. Please note that every piece of information provided in this case study serves a purpose.

2. Once you have completed reading the case study, please read the attached
MIS605_Assessment 2_Additional case information document.

3. Please complete the following tasks:

Task 1.
Create and document a Context Diagram for the System.

Task 2.
Create and document a Level 0 Data Flow Diagram (DFD). The Level 0 DFD should contain all the major high-level processes of the System and how these processes are interrelated.

Task 3.
Select three major and non-trivial processes from Level 0 DFD, decompose each of the processes into a more explicit Level 1 DFD.

Task 4.
Using your own experience with similar online student enrolment systems and the information provided in the case study:
(i) Identify all the entities and their relationships in the System
(ii) Create and document an Entity Relationship Diagram (ERD) for the System.

Note: the case study has not and does not intend to provide a comprehensive description of entities in the System. You are expected to use your own experience with information systems in general and online student enrolment systems in particular to develop this ERD. For example, would Subject Name be an attribute for a Subject? Would Date of Birth be an attribute for Students?

Task 5.
Should data be stored in files in a file system or in a database for the System? Justify your answer.

Task 6.
Translate the ERD you developed in Task 4 into a physical relational database design. Document database tables and their relationship in MSWord file. Normalise your database design to the Third Normal Form (3NF).

4. Please note that your responses to the tasks above must relate to the case study provided.

Instructions to make the assignment: 1. Use Lucidchart software to make diagrams 2. I have attached a solution for the first assignment you will be needing in order to make a second assignment. 3. The assignment says to write 2500 words but write only around 1500 and words should not be about definitions of each diagram. You have to explain what each diagram is doing step by step. 4. There are two case studies attached, one is from the first assignment and second one is additional information to that case study.
