other and can be queried in complex way to extract relevant and meaningful information. The querying of a relational database is done using a high level language called SQL which stands for structured query language. SQL is very easy to understand and unlike traditional programming languages does not rely on arcane syntax, rather structured query language uses English like meaningful syntax in its operations.

achieve high query performance using XML data repositories, since queries are answered by traversing many individual element-to-element links requiring multiple index lookups [23] . In the case of XML data, queries are even more complex because they may contain regular path expressions [24]. Thus additional flexibility is needed in order to traverse data whose structure is irregular or partially unknown to the user. Another option for managing semistructured data is to store and query it with a relational
