Abstract: The invention provides an address list system and a method for implementing an address list. The system includes at least one data input end and at least one inquiry end. The data input end includes a first input unit, a first data processing unit, a first storage unit and a transmitting unit. The inquiry unit includes a receiving unit, a second storage unit, a second data processing unit and an inquiry unit. The address list information of the inquiry end is displayed in a tree structure. In accordance with the address list implementation method, address list information is input at the data input end to form and store data files having uniform format. Data is prepared at the data input terminal. The data input terminal interacts with the inquiry terminal to update data files of a uniform data format in the inquiry terminal. A tree-like address list is formed at the inquiry terminal.

Abstract: An address list system, which comprises at least one data input terminal and at least one inquiry terminal, the data input terminal comprising: a first input unit, a first data processing unit, a first storage unit, and a transmitting unit; the inquiry terminal comprising: a receiving unit, a second storage unit, a second data processing unit, and an inquiry unit. The address list information at the inquiry terminal is displayed in a treelike structure. A method of implementing the address list, which comprises the following steps: A. inputting address list information at the data input terminal and forming and storing data files of a uniform format; B. preparing data at the data input terminal, and the data input terminal interacting with the inquiry terminal to update data files of a uniform data format in the inquiry terminal; C. forming a treelike address list at the inquiry terminal.
