    XML versus Disconnected Recordset


    Hi all,

    I'm working on a client-server app which needs to be converted to n-tier
    application. It's written totally in VB6 with Oracle backend.
    Since we are rewriting it I want to know if I should use XML pass data between
    my business tier and presentation tier. If yes then what are it's advantages
    over disconnected recordsets. This is a corporate application used all over
    the world, so the important issue here is data transfer speed.
    Can anyone out there share their experience in this kind of stuff? Are there
    any performance tests on these parameters?

    Thanks
    Yogesh

    Re: XML versus Disconnected Recordset


    I have created an application that pulls data from a server in Germany creates
    xml on that server(not using ADO to XML - hand coded) and sends it (xml/http)
    to an applet running in a browser (56k line) in the USA. It is pretty quick.
    Now when I run the same app with the data access (not disconnected recordset)
    on my machine (USA) and the database int Germany it runs somewhat slower.
    So somethings to consider: Hardware (server and client), connections, how
    much data is being transmitted, where processes run. XML is much more flexible
    while ADO will take less less steps.
