The QC Client/Server architecture is a 3-tier architecture (web server, application server and database server). The figure below shows the interaction between the components. They consist of:
• Client application: the QC GUI front-end that you use when accessing Quality Center through your browser. Or any other application that communicates with QC using the API;
• Web server: the QC communication between the client and the server are performed using the HTTP protocol;
• Application server: by default, the JBOSS application server is installed with Quality Center. the QC application is built using Java and requires a J2EE application server. The J2EE platform is particularly well designed for client/server applications over the Internet
• Quality Center application: developed to be executed on a J2EE application server;
• Database Server: the database that holds the Quality Center information.
