It's only about 20 bytes top to put on the wire... and some fields change more than others, some not at all. Document reference details don't change that much - ie invoice number Invoice amounts probably do, so it's possible to update those. The protocol goes a bit like this: "update Invoice#=204565 Amount$=67.23" Yes, it should be a soap packet I know, or a WS. But that makes it much more complicated. We just put it on one transmission line. > Or do you only store data as XML that is never updated?

Those are the new-high tech fangly things... they weren't around back then and to this day I sadly profess that I don't have any idea how they work. Hey, don't forget, I'm obsolete and have been offshored also.. :-) > That would allow you to store it as XML and query it without > having to break out fields for storage in relational columns. Maybe... but I like sql databases like mysql, oracle, db2, sql-server etc.. while I might be a critical of isam inspired accounting system designs.. to me, sql is a perfect solution to making that ugly old world of isam go away, or at least be hidden from view. Doing inventory purely in xml is not nice. I can't see any easy way to make that happen. No matter how many good ideas there are, it's still a swamp... and it's always going to be a swamp... I can't see any way past that no matter how many nice walkways somebody wants to install...
