The core of the web system is the web server. The web server software is installed on a hardware server device to form a web server. The web server adopts ADO, ODBC and other technologies to connect with external resources (database)It uses HTML, XML, Java, JavaScript and other development tools to make an information resource system.

Applications of some frameworks: applications of vue.js, angular.js, node.js and other frameworks.
