Flow Chart:

A diagram of the sequence of movements or actions of people or things involved ina complex system or activity.

Flow Chart:

It displays the flow of the system. Here user can be entering query to search engine.after the search engine to search the keywords. The user can be getting the exactedresult.

Use case Diagram:

A Use case represents the functionality of the system.

Here 1 actor like user. This actor can interact with use cases. Actor user can maintain all the usecases of actors. User can search data by using searchengine.

Use Case Diagram:

Class Diagram:

There are 2 classes in this project. The search class can interact withresult class and access the user methods and attributes. Search class is the childclass of search super class and file details class is the sub class of result. The search

class aggregation will display the relationship with result class attributes andmethods.

Sequence Diagram

It displays the time sequence of the objects participating in the interaction .

User objects interact with search engine. The user enters in to query. The user

search to search engine to the specified links. The search engine getting the exact

result to user.

Collaboration Diagram:

It displays the organization of the objects in each class. Here the user objects can organize the search with search engine and the search engine classobjects can organize to the user.

Component diagram:

This diagram can view the main components of the project for deploying.

Here search engine is major component this component can contain all thefiles related to user. These all details can maintain the search engine component.

Activity Diagram:

It displays the flow of the system. Here user can be entering thekeywords after the search to search engine. The search engine can be search tospecified links for user. The finally user can get the exacted result.

State chart diagram:

It will display the objects state in each class here the user class can contain thekeywords. Enter query class can displays the exacted result.

It displays the deployment components in the project. Here the main soft warecomponents are for storing the user data permanently in backend. And one moresoftware is for user interaction for application that is front end.
