Please explain what you want out of this "task management" diagram more thoroughly and give an idea of how experienced with e-r diagrams you are.
the main aim of Task Management is that when an MNC gets a task(lets say a project)
at any point of time the director,or the PM,PL,TL, shoiuld be able to view the status of the
project, what r the things tht has been completed etc.
and also at any point of time the developers(or TL,PL,PM) can see only the status of his work & their sub-ordinates .
like this we have to keep track of many tasks tht will be taking place in an MNC & also the tasks with highest priority has to be finished first ( i.e the current low priority work has to be stopped at tht stage & high priority task has to be taken up)
I know basics like : Types of Relations, Representing entities, attributes
So far i haven't done any exercise on ER -Diagrams
