Ross, Yes, there is a real-world application to the question, at least one where I may try to 'sell' the solution after the theory is worked out. 3 Different systems play with the same live Inventory of products: a UniVerse based OLTP, a MS SQL db based web-order portal, and a Warehouse Control System which fills the orders and receives stock. At night we batch the daily stock receipts from WCS up to UniVerse, update the Avail to Sell qty for the OLTP and allocate Order Reserve Qty to backorders. Then UV sends the updated ATS to the web database (which is always 24 hours behind).
Ross has asked the most astute question in all this, that of data collisions, where the same product is updated on 2 or 3 sides at once. This is perhaps the question that looms largest and keeps people (like us) in batch mode rather than real-time. Thanks everyone for the very worthy contributions to this science. -Baker -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ross Ferris Sent: Wednesday, October 24, 2007 1:58 AM To: u2-users@listserver.u2ug.org Subject: RE: [U2] Fastest Bi-Directional data transfer btwn MV and non MV dbms Baker, How "live" and "active" is this bi-directional transfer likely to be? Do you need to consider the possibility of data collisions (ie: will someone change a record in your UV database that could also be changed on the "other" end) .... OR are the discrete changes somewhat "atomic transactions", with no chance of duplication Are both systems running "live" databases? What are you REALLY trying to do (your question is nearly as big as Texas) ... if you have some specific goal in mind, then some potential road blocks may be removed (or emerge) Ross Ferris Stamina Software Visage > Better by Design! ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
