Local Structural Storage on Software Based Description Technology

In order to more easily develop applications such as webwidget and webapp,based on XML(HTML) to describe and to be complemented by the scripting like JavaScript,can be constructed off-line applications.This is WPF,webOS the basis of technologies such as ideology,false to test the safety of such software applications can not be allowed to directly operation of the local file system, through a layer of abstraction to meet the general objective of the application development.This article is by analyzing the HTML5 standard,thus described the client-based structure to provide a unified storage solutions.HTML5 standard interface on the database is still only partially implemented in the browser,but as technology development,there will be more browser to join this standard,in the future of the web browser-based application development can be taken to HTML5 standard database interface.
