Oh ok.

That's right. At the moment, in my customer environments, data is just  
thrown away in the hundreds of megabytes weekly. Most of it falls  
outside of the ability of the businesses to be able to process it.

As businesses have become more efficient at generating the data, the  
reverse is not always true for receiving it and loading it into some  
managable form.

Ok. Fortunately I work in less tightly coupled systems with smaller  
companies who are less involved in the message elements down at that  
level.
