XRX - The Implementation Process under XRX Architecture

Cristina Nemeş, Marius Podean, Lucia Rusu


The XRX (XForms - REST - XQuery) architecture is a three tier architecture which uses at each tier data in XML format. This offers a great advantage because data is not being transformed in different other formats in order to communicate with other layers. Using this architecture the application becomes more agile, flexible and simple because there is no need of translations like in the classical architecture. This paper describes the implementation process of an application developed under the XRX architecture using W3C standards (XHTML, XML, XPath, XQuery, XSLT, XForms), REST interfaces and a native XML database.
