I've been working with a user on replacing their current web store with one that actually integrates with their System i POS system. Their old one printed an order form off, and they had to pick up the printer output, manually check inventory, grab it, complete the order, then notify the customer. If anything went wrong, they had to notify the customer. It was all asynchronous, which is not what most customers expect from a web transaction.
I've just discovered another use for Twitter.
I've been on Twitter for over a month, now, and I think I'm only now starting to "get" it. I've been lurking, looking, and seldom tweeting at first, but now I'm starting to get the idea of some of what I can do with it and what it can do for me
Recently we had a customer with a large amount of data on an AS/400 on optical drives. They had an application on the AS/400 that would let them read and process this data so that they could view historical information. They had migrated their application to another system, but compliance regulations (and collections) required them to retain access to their historical data.
