DATA FLOW DIAGRAM(DFD) :
A Data Flow Diagram (DFD) is a traditional way to visualize the
information flows within a system. A neat and clear DFD can depict
a good amount of the system requirements graphically. It can be
manual, automated, or a combination of both.
ZERO-LEVEL DATA FLOW DIAGRAM :
Zero -level dfd is also known as fundamental system model, or
context diagram which represents the entire software requirement
as a single bubble with input and output data denoted by incoming
and outgoing arrows.

ONE-LEVEL DATA FLOW DIAGRAM :
In 1-level DFD, a context diagram is decomposed into multiple
bubbles/processes. In this level, we highlight the main objectives of the
system and breakdown the high-level process of 0-level DFD into
subprocesses

USE CASE DIAGRAM :
The use case diagram shows the sample behaviour of the software. It includes the
project functions using use case ,actors and their connections. Moreover the diagram
assist you to define and organize project needs.
This also provides a clear picture of the user and the system relationships.
Connecter: It shows connectivity between activities & persons.
Attribute : it represents the activity performed by the person.
Person: it represents the person who performs the activities on the software.
USER MODULE :- The user is connected with five different use cases which are log in ,
