Hi Sander As always, I guess I'm going to answer your question with a question; Is there any conceivable reason to normalise the data? Is this database ever going to be used for data entry? It sounds like it's more of a data processing facility than a database as such. I'm no normalisation guru, but I have to say I'm favouring your approach from what you've said.

PLEASE ADVISE Hi group, I've worked on several projects where interfaces (text messages) where imported (from customers/third parties) and exported (to custumers/third parties). I've always seen/developed the database using tables with the exact layout of the interface. So if an interface has 4 fields (orderid, article, price, date) like this: orderid article price date 22654hammer20.5020040526 I would create a table with these 4 fields, add some extra columns (imported date, last updated, + some columns to link to other tables for master-detail lines etc.) Now I'm in the proces of developing a completely new system and these guys want to normalize all data. So the complete message is going to be scrambled into bits and pieces. Somehow I cannot find any good arguments to convince them that this is NOT a good approach. The only thing I seem to have accomplished is that the understand the risk of these interfaces changing (wich WILL happen) over time. Questions: Is my approach correct/the better one? Why? Any ideas?
