CHAPTER 2
THEORETICAL FOUNDATION
2.1 Theoretical Foundation
The theoretical foundation describes all the theories used in developing this system.
There are several items to be explained in this section.
2.1.1 Flow Chart
“A flowchart is a pictographic representation showing all the steps of a process.” [4].
A
Flowchart, according to Whitten [4], is used for:
1. Defining and analyzing processes (example: What is the registration process for
entering freshmen students?)
2. Building a step-by-step picture of the process for analysis, discussion, or
communication purposes (example: Is it possible to shorten the length of time it
takes for a student to complete the program?)
3. Defining, standardizing, or finding areas for improvement in a process
2.1.2 Use Case
Use case is a sequence of steps defining the behaviors of the system whether it is
automated or manual. There are several aspects of use case which is explained below.
