Page 19 Conclusions A holistic approach that addresses the need of the whole development cycle XML design becomes a part of application design right at the beginning With ezXML Designer, designs can be formulated using only UML concepts Just like data, designs need to be managed With ezXML DTD Editor, designs can be changed as well as stored in and retrieved from either a file system or a database system DOM and SAX approaches to XML application development is too low level Significant productivity gain can be obtained using a higher level interface to XML With ezXML Java API Generator, high level API can be generated for use by Java applications
