FSE Module 3 - Requirements Engineering Part 2

CSEB233 Fundamental of SE , Module 3 Requirements Engineering Part 2
Requirement/analysis model
A graphical representation of business processes, the problems to be solved, and the new proposed product (software).

Objectives :
-to describe software requirements
-to establish a basis for the creation of a software design

Requirement analysis model
Categorizes into two main level of details
1. Context modeling
2. Technical modeling

Approach for technical modeling
1. Structure analysis
2. Object-oriented analysis

Approach
-scenario –based(use case)

-class based

-behavioral
1. make a list of the different states of a system
2. indicate how the system makes a transition from one state t another

State diagram
-the state of each class as the system performs its function and as observed from the outside as the sysyem performs its function.

In this chapter,rules of thumb topic just a further studies.As for requirements modeling principle, if we know the objective of the requirement/analysis model, we will automatically understood it as well.
I will suggest that ask the students question at the end of the class and for those who can really answer ti correctly, give them bonus marks.
