B. XML in Web Data Mining Application
XML in Web data mining applications from broad terms can be divided into the following four categories: The first category, need for Web clients two or more heterogeneous applications to communicate between databases, as XML allows different sources of structured data very easily together. XML applied to customer needs with a variety of data sources to interact, the data may come from different databases, they have different complex formats. However, these databases between the client and only interact through a standard language that is XML. As the self-defining XML and scalability, it is sufficient to express all types of data. Customers can receive the data processing can also be passed between different databases.
The second category, the majority of trying to handle the load from a Web server to Web client-side applications that customers can choose according to their own needs and the production of different applications to handle data, while the server need only send a single XML file.
The third category needs to extend an open XML through a simple way to describe structured data applications, XML is widely used to describe the user interface. XML describes the data itself. As the data show that separation of content, XML-defined data display allows you to specify different ways to make data more rationally demonstrated. Local data can be customer-configured, the user selection or other criteria to dynamically determine the manner shown. By XML, data can be granular updated. Whenever a part of the data after the changes, do not need to resend the entire structure of data.
