Purpose: Describe your analysis by creating use case and data flow

diagrams. Please be reminded that the use diagram is to describe the

functionalities$/$requirement of your system and the data flow diagram is to

depict the data conversion between processes and the external entities.

The analysis phase is going to establish a logical model of your system

the functions$/$system requirements of your application. You need to

specify what functions your system can offer, not how the system is

implemented.

Instruction:

According to your system planning documents, draw use case diagrams

and data flow diagrams $($context diagram and Level $1$ diagram$)$ for the

information system that you proposed in Phase I&$2.$

The use case diagram should have "includes" and "extends" links

when necessary. You need to provide a description$/$explanation for

each use case and the diagram. For example, a Login use case:

The user needs to provide login credential such as email and pass

to be verified as a valid user.

diagram$)$ and one level $1$ diagram. You need to provide a

description$/$explanation of the diagram so that the reader can

understand how the data is converted between the processes and

external entities.

The things to submit:

A Use case diagram with a description for each use case.

Data flow diagrams. $($Context diagram and level $1$ diagram$)$
