Suppose you want to create a cloud storage service (eg. google drive) named Drive38, which has a Total capacity of 10GB (in which there are two portions Used). Each time a new user creates an account to your service a new storage is constructed for the user. For a new user, the Used portion should be assigned to zero. A user can Upload a file of a certain Site to his 'Drive 38' storage: Uploading a file will increase the Used portion by the Size of the file. A user can extend the Total capacity of lus Drive38 by upgrading (Upgrade) hus user plan. He can also View the status of his storage (Total_capacity, Used)
