  • Patent number: 7617238
    Abstract: A system management method is disclosed for associating a process object and a process with each node in a tree structure, and operating each node based on the tree structure so as to manage the process object and the process, including: registering a registered user that performs operations for a general node corresponding to the process object or for a function node corresponding to the process; setting the function node as a child node of the general node corresponding to the process object for which the process corresponding to the function node should be performed, and setting the general node as a parent node of the function node; setting registered user operation authority for each registered user; and, when execution of the process corresponding to the function node is requested by the registered user, causing the function node to execute the process only when the process is permitted by the registered user operation authority, of the registered user requesting the process, set in the general node tha

  • Patent number: 7454421
    Abstract: A database access control apparatus generates and stores an access key based on a user ID of a user apparatus. Then, the database access control apparatus sends the access key to the user apparatus with an address of a proxy process server apparatus. The user apparatus sends the access key to the proxy process server apparatus when making a database access request, and the proxy process server apparatus sends the access key to the database access control apparatus when making a database process request. When receiving the database process request, the database access control apparatus determines whether an access key same as the access key received from the proxy process server apparatus is stored in the database access control apparatus, and accesses the database only if having the access key.
