The way information is exchanged and combined is dramatically affected by the growth of XML and the Internet. XML changes the way databases are used, even the database vendors did not predict these changes a few years ago. Extensions and mechanisms offered by most of the database systems to support the management of XML data. However, the emergence and importance of native XML database could not be replaced by the extensions to the other database systems. Furthermore, another group of researchers state that XML plays a very important role in the database world, especially in marking up data on the web. This study is going to examine the differences between XML and Relational database systems in terms of representing data, the way both systems are queried and the performance of operating queries on both systems. Moreover, the factors and existing differences between XML and relational database are discussed to help the developers choose the better-suited database for their works.
