The invention discloses a web based database virtual storage processing method. The web based database virtual storage processing method comprises the following steps: designing and building a database; creating and deploying the Web engineering by use of the Web technology, and dynamically linking the database to realize Web site access; carrying out adding, deletion, amendment or inquiry to the information of a virtual relationship table on a browser webpage; and carrying out adding, deletion, amendment or inquiry, which are recorded in the virtual relationship table of the database, on the browser webpage. According to the method, the database can be subjected to virtual storage processing on the webpage, and the authority limit problem that a new database table, a revised database table, and recording in the new managing user database table cannot be provided to a user in the Web browser in the Web engineering can be solved, the Web site capacity can be improved, the interaction of the user and a background and the user and the data base can be enhanced, and the web site is enabled to have good user experience.
