Native XML Database design and realization based on MDA

It originated in the use of ROSE tools, based on MDA development system method, when the model conversion was found that the model can not be automatically converted, for example, the length of type need be completed manually in the Relational Database. The paper advanced through XMI standard, XML had self-descriptive and platform-independent, in the XMI/XML platform technology support, platform independent model will be converted into platform specialize model, after model transformation exported XML Schema, the last they were automatically generated XML documents through the XML editor, which will select Native XML Database for the maintenance and management. Through concrete examples verify that the design can realize the length of data types that can automatically convert, and optimize the traditional database, and the data had a higher efficiency.
