The purpose of this paper is to present the results of an initial study about automatically storing XML data in RDBMS. These are some research about storing given XML data, and most of these approaches based on pre-defined rules and heuristics, without considering application requirement and workload. As the result, the relational schema obtained for given XML is often not optimal for query performance. As a first step, this study was focused on providing an adaptable and adjustable strategy for modelling XML data in relational database systems. This AAM (Adjustable and Adaptable Method) takes advantage of the GA (Genetic Algorithm) to design data schema in RDBMS based on cost-driven approach, we implement and evaluate our approach. Experiments show that this method provides an adaptable and automatic mapping from XML data to physical tables in RDBMS with respect to different users and application requirement.
