PROBLEM DEFINITION


Problem Definition :

The problem is to create the social network that is custamized for the Pondicherry

university. The name of the project is “PU Note Book “. Here, the users i.e students and

faculties should register themselves first. The registered user can login to his page and do

some social networking activities like creating new forum , creating the group , message

to others, chat, etc.,

The administrator of the website will moniter all the activities and he can block

the user who is making some illegal activites like spamming. The admin has to respond

for the queries from the users.

The main purpose of the website is to make good relationship among the students

from various departments and the faculties. This website is having the following

modules.

1. Register

2. Authentication

3. Profile

4. Message

5. Forum

6. Group

7. Search

8. Games

9. Maintenance


USECASE

DIAGRAM


Use-case diagram :

The functionality of a system can be described in a number of different usecases,

each of which represents a specific flow of events in a system. It is a graph of actors, a set of use-

cases enclosed in a boundary, communication, associations between the actors and the use-cases,

and generalization among the use-cases.

Use case definition :Description:A use case is a set of scenarios tied together by a common user goal. A use case is a behavioural

diagram that shows a set of use case actions and their relationships.The following use cases are

used in social networking.

1.Register

2.Authentication

3.Profile

4.Message

5. Forum

6.Search

7.Games

8.Maintenance

REGISTER USECASE :

It is used to register with the website and allow the user to enter his/her personal

details for the profile.

AUTHENDICATION USECASE :

This use case is used to authenticate the user’s login information with the server.If

the details are valid then the user is redirected to the home page or the use is redirected to the

index page.

PROFILE USECASE :

In this use case, the user can view his profile and edit it. The user can view the

profile of other registered users.

MESSAGE USECASE :


The user can send the message to the other registered users by typing their profile

ID. The user can read or delete the message that he/she got.

FORUM USECASE :

The registered user can create new topic in the forum section. This can be

viewed / edited by the forum post owner and the other visitors can view it and post comment on

it.

SEARCH USECASE :

One of the main purpose of this website is to find people and make friendship.

This use case is used to find the people or page with the given information.

ACTIVITY

DIAGRAM


Activity diagram:

It shows organization and their dependence among the set of components.

These diagrams are particularly useful in connection with workflow and in describing

behavior that has a lot of parallel processing. An activity is a state of doing

something: either a real-world process, or the execution of a software routine.

Description:

Activity diagram provides a way to model the workflow of a development

process. We can also model this code specific information such as class operation

using activity diagram. Activity diagrams can model different types of diagrams.

There are various tools involved in the activity diagram.

Activity:

An activity represents the performance of a task on duty. It may also represent

the execution of a statement in a procedure.

Decision:

A decision represents a condition on situation during the life of an object,

which it satisfies some condition or waits for an event.

Start state:

It represents the condition explicitly the beginning of a workflow on an

activity.

Object flow:

An object on an activity diagram represents the relationship between activity

and object that creates or uses it.

Synchronization:

It enables us to see a simultaneous workflow in an activity.

End state:

An end state represents a final or terminal state on an activity diagram or state

chart diagram.

CLASS

DIAGRAM


Class diagram :

The UML class diagram is also known as object modeling. It is a static analysis

diagram. These diagrams show the static structure of the model. A class diagram is a

connection of static model elements, such as classes and their relationships, connected as

a graph to each other and to their contents.

Class diagram:

Description:

A class diagram describes the type of objects in system and various

kinds of relationships that exists among them.

Class diagrams and collaboration diagrams are alternate

representations of object models.

During analysis, we use class diagram to show roles and responsibilities of

entities that provide email client system behaviors design. We use to capture the

structure of classes that form the email client system architecture.

The classes used in SOCIAL NETWORKING are:

1. Auth

2. Profile

3. Visitor

4. Forum

5. Comment

6. Status

7. Game

8. Message

A class diagram is represented as:

<<Class name>>

<<Attribute 1>>

<<Attribute n>>

<<Operation ()>>

SEQUENCE

DIAGRAM


Sequence diagram :

Description:

A sequence diagram is a graphical view of scenario that shows object

interaction in a time based sequence what happens first what happens next. Sequence

diagrams are closely related to collaboration diagram. The main difference between sequence

and collaboration diagram is that sequence diagram show time based interaction while

collaboration diagram shows objects associated with each other.

Object:

An object has state, behavior and identity. An object is not based is referred to

as an instance.

The various objects in SOCIAL NETWORKING are:

User

Website

Login

Groups

The sequence diagram for the forum, message and profile are given in the following diagrams.

COLLABORATION

DIAGRAM


Collaboration diagram:

Description:

Collaboration diagram and sequence diagrams are alternate representations of

an interaction. A collaboration diagram is an interaction diagram that shows the order

of messages that implement an operation or a transaction. Collaboration diagram is an

interaction diagram that shows the order of messages that implement an operation or a

transaction. Collaboration diagram shows object s, their links and their messages.

They can also contain simple class instances and class utility instances. During, analysis

indicates the semantics of the primary and secondary interactions. Design, shows the semantics

of mechanisms in the logical design of

system.

Toggling between the sequence and collaboration diagrams When we work in either a

sequence or collaboration diagram, it is possible to view the corresponding diagram by pressing

F5 key.

The collaboration diagram for the social networking site is give below for the forum,

message and profile.

Conclusion :

Thus the project ”PU NoteBook” has been successfully created

and its use case, activity, class, sequence and collaboration diagram are drawn.

They have been given in this document. In future, the website will be extended to

be accessed by the mobile without internet connection. This is possible by creating

the mobile server which will respond to the sms request from the registered user’s

mobile.
