ER diagrams

[pdj2]

can anyone draw these ER diagrams?

1. Construct an E-R diagram for a university registrar’s office. The office maintains data about each class, including the instructor, enrollment, time and place of class meetings. For each student pair, a grade is recorded
2. Construct an E-R diagram for a car-insurance company that has a set of customers, each of whom owns one or more cars. Each car has associated with it zero to any number of accidents. Also create a relational database for this.
3. Construct an E-R diagram for a hospital with a set of patients and a set of medical doctors. Associate with each patient a log of the various tests and examinations conducted.

What the fuck are you talking about.

Agree.

I think she's talking about entity relationship models.

That's just a guess but.

Why not do your homework yourself? You may actually find it to be useful when doing slightly more advanced stuff at uni that you actually know how to do an ER diagram.

When i was a poor lazy student i skipped over the ER diagram part of my course and then had to learn it all again 3 months later when modelling databases.

Lolz, aha.

We call 'em somthing else here.

I do know how to do that, on account of actually having learned how to do it, myself.

So no, I'm not doing someone else's homework so they don't have to study.

Fuck sake 4Play ya lazy bastard.

In other news, good draw in the champs league. You must fancy your chances of winning it this year.

I heard they already put our name on it so i dont know why they are even bothering with the other games now.

:lol:

We can beat Barca, we really can. Honestly it can happen, we've done it before.

you lot getting the better of barca over two legs is going be a big challenge.

Though i would like to see it happen.

It would be fantastic, but I can't really see it happening.

Two good performances is all we can really ask for. Maybe even get a win over them at Parkhead. We can do that, it's amazing the difference in Celtic home and away in Europe.

I think you have an excellent chance this year. Final minimum is my guess.

Probably playing Barcelona.

you playing the final leg in the nou camp won't help your cause much either.

I would love to see us win the champions league since i don't think we will be consistent enough this year to beat arsenal or united to the premiership.

I tend to agree with that, both parts actually.

You must fancy picking up the Carling as well. Isn't it a tradition for your managers to pick that up first, as a sort of practice for better things.

Yeah i can see us beating Everton and then meeting arsenal in the final. I would much prefer Tottenham though. Local derbies with them always have the best atmosphere and they would be easier to beat.

The Chelsea v Arsenal final was an excellent game. Pity about the wee bit of bother but an ace game of football to watch.
