Object Oriented programming is all about reuse so our java guys made a 
universal update statement that updates all columns in a table, even unchanged 
columns. I know its bad, but its a major re-write to change this. I was digging 
through the otn docs and some books and everything that leads me to this 
requires a significant amount of reading. Multiple chapters etc...
anyone know a short article that explains undo and redo along with diagrams and 
why its bad to update unchanged columns that is easy for a non-oracle person to 

checked the concepts doc, but they would probably have to read 50-70 pages to 
get the basic idea.
