Parts of the thread about standard APIs for XML storage seem to have fallen into a black hole. Searching the xml-dev digest's author index for gopi (gopi@a...), I find neither his original post nor his replies. The question and reply (below) seem to have dropped into a hole. In an earlier message, I noted that some companies are developing ODBC and JDBC drivers for XML files. This elicited a reply from gopi: > If I am not understanding it wrong, these drivers will be similar to XQL or > XPath processor, in general another "Query Processor". Not exactly. If an ODBC or JDBC client connects to an SQL server such as Informix, DB2, Oracle, etc., the storage engine and query optimizer are part of the SQL server. For a data source such as a text or XML file, that's not the case. There is no database engine or optimizer in a text file, so a driver for that type of data source includes an optimizing SQL engine. All of this is transparent to your source code. There's more info in a DBMS magazine article (March 1994): http://www.dbmsmag.com/9403d13.html ================== Ken North ============================= http://ourworld.compuserve.com/homepages/Ken_North =========================================================== *************************************************************************** This is xml-dev, the mailing list for XML developers.
