DATABASE UML REPRESENTATION

Question

Hi,
I have a database and want to use UML Notations to make a EER Diagram of it.
Which tool is easy to use. I have already used microfost visio(gives an headache while using different arrows)

I'm trying to write a UML class diagram to
demonstrate the relationship of some classes.
Now I have the following construct:
class A{ ... }
class C{ ... }
class B {
the returned collection contains C's
public Collection getCofA(A){ ... }
There is insufficient Java here to determine the UML class diagra, (beyond the three obvious class boxes). a Class diagram shows the static relationship between the classes. So the last line does not add anythng.
so one can think of it as A having C's,If A is a collection of C's this would be represented by the composite line if there is a return ref from each C to the A, or by the association line is there is no return reference. Multiplicity (0..*|1..*|N) would be is shown at the side with the multiplicity. C.
Composition
C aC = new C(this) ;
aA.addC( aC ) ;
Association
C aC = new C() ;
aA.addC( aC ) ;
but there is no A.getC() or A.Ccollection ... but one
uses the class B to represent the connection between > A and C.This is represented by an associative class. There are at least three seperate ways to show this in common use.
1) link the two classes with a straight line. Draw a broken/dotted line off this line to the connection class.
2) as 1 , except a diamond is added at the junction between broken and full line.
3)Add a box off the collection handler class, make the association from this to the contained classes.
I tend to use the final method
How would one represent this connection in an UML
class diagram?This really depend on the conventions in use at the site/case tool. Just document your conventions.
