In a data center, the typical computer room/host room space area is divided into:
Total wiring Area (MDA), placing routers, backbone cables, Lan/san switches, PBX switchboard, wiring racks;
Horizontal wiring Area (HDA), the placement of LAN/SAN/KVM switches, wiring racks;
Regional wiring Area (ZDA), placement of had and EDA in the middle of the extension of the area over the Line box/integration p

Taking the comprehensive office building of a bank as an example, this paper describes the application of the integrated wiring in the financial building.
Project Overview
A bank is a large commercial bank. Comprehensive office building total area of 22600 square meters, 16 floors above ground, 2 floors underground, and 1 to 4 floors for the podium, 5 layer above all are standard layer. Take 6 layer as an exampl

Equipment is set up in the appropriate location of each building to line equipment, network management and management personnel on duty. The subsystem of the equipment should be composed of the building line equipment of the integrated wiring system, the telephone, the data, the computer and so on and the security wiring equipment. The telephone, data, computer mainframe equipment and security

Second, create a table using the Database Wizard
Chinese Access 2000 provides two ways to create a table: To create an empty table for entering data, and to create a table by using data that is already in another data source. You can use the Database Wizard to create all the tables, forms, and reports that are required for the database in the operation of the database. You might think that this is similar to using the project manager
