Handing your homework to us, and then asking us to do it for you, does you no favours at all. The diagram appears completely meaningless to me (and I suspect most others). Is it database related?

Why not try and do a bit of the work yourself and then ask for comments.

Why are you asking a database forum for help on a project management task?

Imagine the letters (nodes) as subtasks in a larger project. Some tasks need to be done before others.

Start with a node that has no predecessors - I'll give you a hint here it's A.

Find all the nodes that are solely dependant on the nodes you've put down so far ie B and link them up.

Repeat this process until you run out of nodes then stop. I'll give another hint - the last one is L.

To get bonus marks you could work out how long the whole task will take assuming subtasks can be done in parallel.
It took me 2 mins to scan your link and complete your coursework yet you go to the lectures (I assume) and seem to be thrown. It may be worth taking a long hard look at whatever subject you are studying and deciding whether it's for you. On the positive side, if it's project management your studying, then at least you've worked out the main point is to get others to do the work for you

thanks for your reply...

by the way, it's not really my homework or anything else, i'm just curious about it, and i know someday it would be useful for me when i'm on project management.

Careful with your responses to our contributers, Jan.



I agree with blindman; this question doesn't actually have anything to do with databases.

I'm too busy right now to bother helping him look foolish. He'll just have to continue on his own.
