| web architecture of xml is too simple a client send a request to the server in a predefined format and receives the appropriate response. This is possibly because the data stored in an XML document does not assume its intended use. Different applications can extract data according to their customized needs. Since XML is used to exchange data between various web applications, the coupling between the server applications and the client applications is relatively loose. XML can encode non-relational data, as well as relational data structure. This enables the server applications to extract data from any data source, and helps the programmers to quickly build applications for the manipulations of that data.
