Suggestions and Requests / Changing default value for line style

« on: October 03, 2006, 09:55:22 am »

It would be really helpful if one could change the default line style value for object and control flow arrows. I produce fairly complex activity diagrams and and the control flow arrows usually need manual readjustment. All that additional clicking gets so mechanistic.

In fact, why not have arrows that automatically wrap around the other objects? The direct route just draws right over everything.

Many thanks

Suggestions and Requests / Changing default colours for objects

« on: October 03, 2006, 09:57:26 am »

Hi there,

I like to change the colours of the various object classes in my diagrams for clarity; actions a different colour from activities for example. Unfortunately EA does not allow me to change the default colours for these objects and I have to manually change each one. It would be really useful to be able to change these default settings.

Cheers

I notice that forign key generation from ODBC and other sources seems to have been a bit buggy in the past. See builds 657, 606 and release 3.00

(I'm on build 806 by the way...)

I've not tried a different driver - out set-up is such that it would be problematic. The driver works well in all other situations mind you. Hmmmm!

Hi there Paolo. I'm using Sybase ASE.

General Board / Data schemas with foreign keys

« on: December 20, 2007, 03:44:57 am »

Hi there,

I'm attempting to generate an ER diagram from an existing database via ODBC. I am able to connect and generate classes for the existing tables, but the foreign keys do not generate, leaving me with a series of unconnected classes. I can't find an option that seems to be explicitly preventing this, so am not sure why it is happening.

Relationships do generate between views and tables, but that's not what I'm after, just the foreign keys.

Can anyone explain how to generate forign key relationships?

thanks! Dave

General Board / error importing a data diagram

« on: November 22, 2006, 02:50:21 am »

Morning,

I'm attempting to generate and entity-relationship diagram from a ODBC link to a Sybase database. EA reads the database but once I select the tables and click import, the only result is a message box with a load of ascii squares. Anyone encountered problems in this area before?

many thanks

General Board / Re: Separating diagrams in a package

« on: October 31, 2006, 07:15:56 am »

bump . . .

Any ideas, expert UMLers? How do I separate out diagrams within one instance of EA? Opening new instances is starting to become a pain . . .

thanks

General Board / Separating diagrams in a package

« on: October 26, 2006, 09:57:27 am »

Hi there,

I'm working on a project to model the work of several different professionals. I intend to produce multiple diagrams for each; say an activity diagram, an analysis and a use case diagram. There are two points I could use help with

1) How do I keep these separate in one instance of EA? I'd like to have the diagrams first divided into folders by person "Mr A", "Mr B" then again by diagram type, preferably keeping the elements of each diagram in different folders so I can keep track of them. Is this done by packages? The help files aren't really helping.

2) My diagrams are currently split over different instances of EA. I've tried importing them into one instance, but it raises conflicts. How can I import multiple diagrams into one instance and keep them seperate from each other?

thanks

Dave

Thanks midnight, I'll do that. Having to manually change the colour for each object is another of my bug bears . . . .

General Board / Setting options on objects

Yellooo,

Quick question for you all.  How can I set up EA such that the line style of control flow and object flow is custom line by default?

100,000 thanks in advance

General Board / Setting automatic colours for objects

« on: August 03, 2006, 07:56:07 am »

Hello. Nice tech question here, nothing to do with UML at all.

How do I permanently set colours for the different objects? For example, how can I set up EA so actions always appear a certain colour? At the moment I need to manually change each one afterwards.

Any ideas any ideas?

General Board / Representing output documents

« on: July 31, 2006, 09:27:16 am »

Hi there,

I'm working on representing business processes in an activity diagram. At certain points in this process, documents are output (in this case scientific papers but they can be any document at all). I have examples of these papers that I'd like to include in my model. What's the best way to represent a physical output such as a document in an activity model?

I see that deplayment models have a "document" object that I'm using for the moment. How best can I represent a process producing an document output and then carrying on with the process flow?

Many thanks in advance, Dave

General Board / Re: Representing databases in activity diagrams

« on: July 27, 2006, 06:23:16 am »

That's interesting. I'm already using partitions as it happens, as there are multiple user groups working in this process. I suppose a third partition for "database" would work, but what would it contain? A datastore object and that's all?

I would have imagined that representing a database in an activity diagram was a fairly common event though. What is the standard approach for this? As Bary says, debate welcome!

General Board / Re: Representing databases in activity diagrams

Perhaps I've not been clear enough!

I'm modelling a business process, not designing any sort of software. I'm trying to represent the process flow, and how each activity uses and outputs data. Throughout this process a database is used, and is added to and read from as the process continues. So for these purposes I assumed a datastore object with an associated ER diagram would be sufficient.

Datalayers as I understand them are software modules used to interact with your database. Wouldn't a datalayer be used in say a class diagram? That level of detail isn't really required at this stage.

As well as this, it's an Access db, so the datalayer is kind of hidden from me.

Does this make things any clearer?

Erm?

The database participates in as much as it receives and outputs information throughout the activity. I'd like to show this on my activity diagram. I used the datastore object to do this, and now would like to detail it's relational structure also.

For this, the datastore give me the option of a composite diagram, with classes. I'd like to use a data model, with tables.

I suppose I could be missing something here, but it seems logical to represent the database in this way. Do you think not?

thanks, Dave
