You're a joke.

Why don't you quit deferring to the notion of spreadsheets being a presentation element and look at the problem for what it is?

I'm automatically importing spreadsheet data sent from various clients, all of whom will be sending them in different formats. In the scope of my system, what way, other than the fact they are called "spreadsheets", are they being used as a presentation element? Should I cajole the clients to export their spreadsheets to CSV,XML, or maybe YAML to avoid using a presentation element?

Where should one store vital configuration information related to key entities then? Based on your stunning analysis, should I conclude that using a database to store configuration information is wrong? Oh, I hope someone tells all the CMS DB designers that they've been mixing presentation and data layers. Received on Mon Oct 22 2007 - 11:42:16 CDT
