Analysis on Database Connection Mechanism of WEB Application System in Dreamweaver

Dreamweaver has powerful database access functions, using windows operating without coding can operate database. Existing literatures only describe sequential steps, but, the network database connection mechanism and the steps corresponding to program code in WEB system are not further expounded. This paper analyzes database connection mechanism of WEB application system based on three-tier architecture, and the corresponding relationship between main steps and auto-generated code using windows operating to achieve database access in the Dreamweaver development environment, and then discusses two more complex issues associated with database connection in WEB application systems development-principle and realization of transaction processing and database connection pool technology.
