Why is XML superior to other forms of data exchange?
The XML gives universal data format for integrated electronic business solutions. Other database systems and Relational data base system can't meet all the demands of electronic business since they process data independently of its context .
Traditional databases may be appropriated for data which fits in rows and columns, although cannot sufficiently handle rich data as video, audio, nested data structures or complex documents, that are characteristic of typical Web content. To deal along with XML, traditional databases are classically retrofitted with external conversion layers which mimic XML storage by translating this among XML and several other data format. Such conversion is error-prone and results into a great deal of overhead, mainly with rising transaction rates and complex document.
XML databases, conversely, store XML data natively into its structured, hierarchical form. Questions can be resolved much faster since there is no require to map the XML data tree structure to tables. It preserves the hierarchy of the data and raises performance.
