Web based database virtual storage processing method

Abstract

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.

Description

technical field [0001] The invention relates to a web-based database virtual storage processing method, which belongs to the technical field of databases. Background technique [0002] With the rapid development of the Internet, the World Wide Web has also developed rapidly. Changing user needs and data types will seriously restrict the progress of Web project development. It is difficult for a fixed database to meet changing user needs. Therefore, projects often need to dynamically create tables at runtime and dynamically maintain the fields of tables and even the relationship between tables. Dynamically creating and managing database relational tables on web pages can improve the performance of Web sites and strengthen users and the background. and database interaction. [0003] The current Java Web technology, based on the Java object-oriented programming idea, will create a corresponding JavaBean object for each relational table in the database during development, and u...

Problems solved by technology

[0004] However, for the prior art, although technologies such as JDBC (Java Data Base Connectivity, java database connection) and Hibernate can be used in Web engineering to generate relational tables in the database, the JavaBean objects corresponding to the relational tables cannot be automatically coded by programs. Generated, the JavaBean object corresponding to the relational table is usually manually written in the project development stage or artificially reverse-generated using development tools

Since the JavaBean object corresponding to the relationship table cannot be established, the background cannot obtain the instance object corresponding to the newly created relationship table, and then cannot simply add, delete, modify, and check the newly created relationship table and the records in the relationship table. SQL statements to operate on relational tables

This requires users to be proficient in SQL statement knowledge, which obviously cannot meet the needs of most users
