The mentioning relational database system term has become a synonymous to
database system, but the monopoly of big companies that work in database systems field
has become an obsession for persons who work in this field, because of the high costs o
f
this systems. For this reason the concerns turn towards the advanced technique : the native
XML database systems which are free or most of them are open source systems because of
the increasing dependency on XML files and particularly in transporting data between
different applications and the availability of collections of related files. This has
summoned towards a system to manage and organize them, for this reason the NXDs
appeared. The aim of this study is making a comparison between the capabilities of
RDBMS and NXDs in accordance to multiple standards , investing these two techniques
in practical application , make the relevant tests which reflect the use of these techniques
on the suggested application , display the results and give future suggestions.
