System and method for displaying and operating multi-layered item list in browser with supporting of concurrent users

摘要

Support of end-user to view and operate computing resources through logically organized and graphically represented multi-layered item list (“hierarchical list”) has been fully realized on native window based computer user work environment with modern operating system such as Windows Explore of Microsoft. The present invention has implemented such a hierarchical list to represent structured resources, such as for a central controlled distributed scalable virtual machine (CCDSVM), and to be displayable and operable via a browser on an end-user device for user to access and manage the actual structured resources. The implementation of the hierarchical list is accomplished by creating the hierarchical list in memory to mirror the actual structure resource, where the mirrored hierarchical list is sent to the end-user device, where the end-user device executes the browser to display the hierarchical list to allow the user to access the actual structured resources via the displayed hierarchical list.

主权项

1. A server supporting a plurality of users access to remote folder structures, the server comprising:
memory, and non-transitory computer-readable medium comprising program code which, being executed by the server, configures the server to: create a first per user-session hierarchical list in the memory for a user session initiated via a first end-user device by a first one of the users for access to a folder structure served by the server, the first hierarchical list representing the folder structure in a reduced form, the folder structure comprising one or more folders, where each of the one or more folders is used for holding at least one data object, send a user interface comprising the first hierarchical list to the first end-user device to be displayed thereon, the displayed first hierarchical list being navigated by the first one of the users to request access to the folder structure; process the request for access to the folder structure received from the first end-user device, wherein the program code to process the request includes to update the folder structure, and also update the first hierarchical list in the memory to reflect the updated folder structure in accordance to the request,
wherein the server sends an updated user interface comprising the updated first hierarchical list to the first end-user device to be displayed thereon during the user session, and deletes the first hierarchical list from the memory in response to exit of the user session.
