初始的商品信息文件名为porduct，如要利用此系统进行商品信息的管理，系统会提示用户输入商品信息的文件名，则要输入此文件名，或输入管理员使用系统时新建的文件名。如删除该文件，则需在系统中调用相应的功能函数重新创建初始化文件。 初始的用户信息所在的文件名为yonghu，系统默认即为此文件名，不可删除。 -Initial commodity information file named porduct, such as to make use of this system for the management of commodity information, the system prompts the user to enter commodity information file name, will have to enter this file name, or enter the system administrator to use the new file name . Such as delete the file, then call in the system function corresponding to re-create the initialization file. User information where the initial document yonghu, that is, to this end the system default file name, can not delete.
