Project Description:
“ABC” is a worldwide company whose branches are situated all over the world. “ABC” needs an online virtual drive for storage of its important data over the web so that data can be accessible at any branch. They face a lot of problems due to distributed data so they demand an online virtual drive that is web based application which can manage their data problems. Online Virtual Drive will be a Web based application that will help users to store their important data on an online virtual disk drive that will act as similar to our hard disk. All the directories and files would be viewed as similar as we are viewing them on our personal computer’s hard drive. There will be two types of users other than the administrator. Anonymous User and Registered User.
Online Virtual Drive application will have a user-friendly interface. It will fulfill all the user and business requirements of the ABC Company. It will also provide required reports efficiently to the management and will help them in decision making. Anonymous user can access to Help Section, Tell a Friend Section, FAQ Section, About Us Section, Feedback Section and Registration or Sign Up page.
An anonymous user will fill the whole Registration form and will submit it to the administrator. Administrator of the system will have the right to approve or disapprove the user. When Administrator will approve the space requested by Anonymous user and verify all the information provided by Anonymous user in his/her registration form then a confirmation email will be sent to that Anonymous user which will become Registered User. Registered User on approval by administrator first has to login, to use the various functionalities of the system. User can upload files, delete, move and copy/paste files in directories/folders on system. User can make as many directories on system till his/her quota of space is not exceeded.
By Considering the above scenario you are required to draw Object Model for Online Virtual Drive system. UML Object Diagram should be comprehensive and must contain:
1. All possible objects Marks 5
2. Possible attributes for each object Marks 5
3. Operations of each object Marks 5
4. Relationships among different objects for example Inheritance, Aggregation, composition, Association etc. Marks 5
o Assignment should not be copied from net, handouts, books or any fellow.
o Solution should be “Precise”.

i think email and signup can also be a object.

I think email and signup are not object that are attributes of an object.

means Administrator is object signup, email, AssignSpace, etc.. are attributes of this object.

Signup Anonymous ka attribute hai administrator ka nahi

yes signup form will also be an object having attributes like first name, last name, address, Cell # etc. But in my point of view email won't be an object because it ll b considered as the method or responsibility of Anonymous user.

What you think now???? 

object are onlne virtual drive system, company, administrator, anonymous user, registered user, directory , help section, data, email and sign up 

i is also because email is an object the has link with admin and anonymous user and has actions:emailID(),message()

Help Section  object nahi hai

yah attribute hai 

sallam to all

ap sab se request he k jo b solution ya idea ap share karen, wo .doc me karen, q k .docx sab log open ni kr sakty..... like me...

i hope u understand .....

I consider following objects

Anonymous User, Registered User, Admin, File, Directory, Report.

Attributes for each object

Anonymous User (Name, email, address, contact no, father)

Registered User (username, password, id, space)

Admin (username, password, id)

File (Name, size, directory name)

Directory(Name, total Files, space, parentdirectoryName)

Report (Title, detail, Result, suggestion)


Anonymous User:

register, see help_section, tell_a_friend, see_faq, see_about_us, give_feedbck.

Registered User:

Signin, upload_file, delete_file, edit_file_name, create_copy, move_file, create_directory, delete_directory, edit_directory_name, see_space, view_file.


Signin, upload_file, delete_file, edit_file_name, create_copy, move_file, create_directory, delete_directory, edit_directory_name, see_space, view_file, see_ reports, see _users, confirm_user, allote_space.


setName, setDirectoryName, create_copy.


setName, create_subdirectory, add_file, delete_file, move_file, set_Size.


setTitle, setDetail, compile_Result, set_suggestion.

thanks so much for given a link to download a ms visio 2013
