XML DTD (schema) as database schema (DDL)
Folks, I am thinking about using XML DTD (or its schema specification) as a DDL to define schema of a database. Following is the simularity of XML and traditional SQL: DTD database schema a huge XML document database table XML query language SQL small XML document SQL query result HTTP ODBC, JDBC Now logically you are not storing data into traditional SQL table, but as a large XML document. Physically they could still relational database, or object database. The advantage of this is that XML is object-oriented. It is much easy and close to real application to model in XML than SQL. A step farther, one could use XML to model his specific domain and provide a query engine to handle the query and dispatch it to an application module. In this environment, there is not actually physical database but application process running behind the scene. The user will have all the freedom provided by XML query language to manipulate system as he want. No more API. What your thought? Anybody out there build such framework?
