RE: looking for doc with diagrams on redo and undo for java developers

Ryan,

I know for sure Jonathan Lewis covers this in his three-day seminar, = "undo and redo costs". I think it may also be covered in his book, but = I don't have it here at the office today.

Subject: looking for doc with diagrams on redo and undo for java developers

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 follow?=20

checked the concepts doc, but they would probably have to read 50-70 = pages to get the basic idea.=20
