General presentation I had a difficulties when I had to maintain or develop programs with data designs like the one presented underneath:
Click and look at the picture during 5 seconds, no more
Use the button on top of the new window to close it.
In general, you have seen boxes (data) and arrows which link them (connections between data). The problem was that this was becoming too complicated for me because the data and their connections were too numerous.
In this case, one calls colleagues and does big projects, costing a lot of time and the users often end unsatisfied.
But the user wants more because there is the permanent threat that customers will to go to the competitors if a strategic new function cannot be done, immediately.
