In the environment where information exchanges running rapidly,performance becomes a matter that is absolutely necessary to ensure the accuracy and speed of information delivery.Response time and throughput are two of the performance paraeters that could be considered in choosing data storage media. A DBMSA is a set of software progams that controls the organization,storage,management,and retrieval of data in a database.Along with the development of information technology,the needs of DBMS as storage media would be crucial.In addition to DBMS ,there is another data stroge format-had a similar structure to that relationalnamed XML.Nowadays native XML databases had been introduced as a new technology of XML.In native XML database,XML files could be related one to another just like in DBMS.The objective of the research was to analyze what is best between those two data storage format.The analysis result concluded that DBMS lower response time and greater throughput.
