General Board / Re: How to specify multiplicity of parameter?

« on: August 02, 2010, 02:01:36 pm »

Guess I have to upgrade to a new version of EA. In Version 7.5 (Build 854) there is no such button.

Cheers,

General Board / How to specify multiplicity of parameter?

« on: July 30, 2010, 02:59:07 pm »

According to UML 2.1.2 (formal/2007-11-02, ch. 7.3.41) a Parameter is a special MultiplicityElement and thus inter has alias a lower and an upper value.

How can I set these values for a parameter of an Operation in EA?

Thanks in advance,

General Board / Generate a slash if {Att.isOrdered} <> 0

« on: March 17, 2010, 06:05:39 pm »

Hi,

how can I generate a slash, if an attribute is derived, i.e.:
"/ age".

Along these lines:
{Att.isOrdered} <> 0 should generate"{ordered}"
{Att.Const} = "Const" should generate"{readOnly}"

Thx,
Torsten

General Board / Re: Training or Reference material for Spraxs EA

Hi Steve,

okay, I understand.
Unfortunately I haven't used the visio importer either, so I cannot offer any advice on this.

You can attach files to your model elements (see tab "Files"), but I cannot think of any way to import the information contained in your excel and word files.

Best regards,
Torsten

So you have created a "technical reference model" with MS Visio (or MS Word or MS Excel respectively) and now you want to import that Visio file into EA???  :-?

General Board / Merge elements

« on: June 13, 2008, 12:58:52 am »

Hi there,

does EA offer a function to merge two classes?
By mistake I modeled the same class two times. So in some diagrams I used the one class and in other diagrams the other class. Now I want EA to merge these two classes and to replace the original classes with the merged class in all diagrams.

Best regards,

General Board / Re: Ownership of associations ends

Okay, I just found it in the properties dialog of the association:
Tab "Source role" ("Target role" respectively), checkbox "Owned".

General Board / Ownership of associations ends

« on: May 06, 2008, 05:23:31 pm »

Hi,

does EA support the dot-notation (that visualizes whether an association end is owned by the association or the associated classifier) as described in UML Superstructure v,2.1.2, chapter 7.3.3, p. 42?

Thanks in advance,
Torsten

General Board / Re: Do I need to select "Unique" box for a table's Primary Key?

« on: April 24, 2008, 05:09:48 pm »

Hi Craig,

(Unchecking "unique" on a primary key doesn't make much sense, does it?)

I guess I was wrong here. Consider a primary key that consists of two columns named id1 nad id2:

id1 ! id2
----+----
   1 !   1
   1 !   2
   1 !   3

As you can see the primary key is unique but the column id1 is not.

Will the Primary Key not be unique unless the box is checked???

So the answer here is YES.  

Furthermore I found out that EA disables "Not Null" and "Unique" when you check "Primary key" (as I already wrote) but enables them if you select another column in the "Column" list and then select the primary key again.

Quiet strange...

Hi Lipmanc,

When I check "Primary key" EA disables the check boxes "Unique" and "Not null". So I cannot check or uncheck "Unique" while "Primary key" is checked. How do you do this?

I'm using EA 6.5 (Build 804).

General Board / Re: association name in class diagramm

« on: April 17, 2008, 05:11:11 pm »

But the question was not what I recommended but whether it was possible.

Perfectly correct!

Sorry David, I didn't mean to critizise you. I just wanted to be sure, .Net developer knows about the consequences.

Best regards,

Try creating role names for each end and setting the direction.

I wouldn't recommend that.
Consider that role names are different from the association name. EA will use the role name for code generation. Furthermore it is not compaint with the UML specification (at least to my knowledge).

If you want to descibe the association in more detail you can use the "Notes" in the property dialog of the association or create an "external" note.

General Board / Re: How to link multiple elments with the same not

« on: April 16, 2008, 05:19:28 pm »

Hi Toolman,

alternatively you can copy the note into the clipboard and paste it into every diagram you need. Then you can connect the note with the elements shown in the diagram by creating a NoteLink (a connector).

Best regards,

General Board / Re: Reverse Engineering - "new" Relation not

« on: April 15, 2008, 07:12:48 pm »

Hi,

it must be modeled as a dependency, because you don't need that member variable. The stereotype of the dependency should be <<use>>, because your class Program does not only create an instance of SecondClass but also invokes an operation on it (see class Usage in der UML superstructure).

If Program just instantiates SecondClass I recommend the stereotypes <<instantiate>> or <<create>> whatever you like best.

Best regards,

Bugs and Issues / Setting BehaviorStateMachines::State::submachine

« on: July 30, 2010, 07:52:56 pm »

You can create a State and mark it as being a Submachine state (as defined in formal/2007-11-02, ch. 15.3.11) by setting the custom property "isSubmachineState" to "true".

But there is no way of specifying the state machine that is be inserted in place of that submachine state (that is, to set a value for BehaviorStateMachines::State::submachine)

The bug has been detected in Version 7.5, Build 845.
