General Board / Re: How To link element to attribute of other elem
« on: January 26, 2005, 05:52:57 am »
Thanks for the feedback, folks.

Here's what I've found works the best (for me) so far:

In my domain model,  I model everything as distinct elements (currently using class elements).  So say we have students and they have names, I create a "student" class, a "student name" class.

So, anything (db table, gui control, report field, etc.) that <<depends>> on the definition of "student name" can be discovered via relationship matrix.

Although it's nice to have attributes "externalized" as their own elements, I'm still trying to decide whether or not the effort has any value other than that and the matrix.

added ->> Here's a thought:  would externalizing attributes this way help understand the domain better?

G'day,

This would apply to construction phase during development and to the maintenance cycle too.

For example, say the size of a database column increases.  I'd like to quickly identify all those (already created and tested/signed-off) screen data fields that need to have their "size" properties increased.

G'day folks,

I'm using EA to document the database requirements (and layout, etc.) of screens.  Those screens have fields that show values selected from table columns (aka attributes).

If I make changes to some table column, then that may have an impact on fields such that the fields require some changes to their properties.

Anybody can think of a good way to create a link between screen fields and table columns (aka attributes) such that I can use the Relationship Matrix to manage the impact of database table column changes on screen fields that display values from those columns?

This question relates to one I posted earlier: http://www.sparxsystems.com.au/cgi-bin/yabb/YaBB.pl?board=general;action=display;num=1095189133;start=7#7.

I'm hoping that I've described a better scenario for my problem, in the hopes of generating some more (much appreciated) ideas.

Not in my case. They start with "component view"....


Sorry, I don't have much experience with any of your questions, but I will take a crack at the above.

Sounds like your elements are located directly in the "component view" package.  Try creating a package in the "component view" and moving the elements into that package.  Hope that fixes things.

G'day,

If you don't have Adobe Acrobat, download and try Win2PDF at http://www.daneprairie.com/products/win2pdf.htm

Some would say "terrible 2's", I say "what a little trooper".

Start 'em young.  Goes to show, even two year olds love to play with EA...

General Board / Re: How to copy functions between class diagrams?
« on: December 22, 2004, 09:16:07 am »
G'day,

If your current diagram is showing Class_A, then you can, from the project browser, drag an operation/attribute from Class_B onto Class_A on your current diagram.

Ooops, my apologies, airmie is right, table can definitely be dropped as an instance (i.e. object).  Not quite sure I like the results.

I still think Generalization is the way to go.  I just checked, and I can draw a Generalization link between a class and a (class stereotyped as) table that I reverse-engineered.  NOTE that any attributes inherited via Generalization will not be included in DDL generation.

G'day,

I don't think EA can create instances of database tables.

Would it suit your needs to link your reverse-engineered tables via "Generalization" link to your "Application System Table" class?

G'day,

I answered the same question in Larry's other post:

I can't figure out a way to natively print a section of a diagram in EA.  I would suggest that it would be wise to split your super-large diagram into many smaller ones.  They could be put back together as a large diagram with (look in EA's help index) "Hyperlinks" (using frames, which essentially gives you diagrams within diagrams).
 
Alternatively, you could use something like SnagIt, a screen capture utility that lets you grab any area on your monitor for capture and printing.

G'day,

Larry, I'd suggest that you put in a feature request to Sparx to provide an "ERD display option (non-standard UML)" for data modeling.  If it's easy enough for Sparx to implement, maybe they can attract some more ERD modellers...  I'm not sure I like the idea, but hey, I wouldn't have to use it.

G'day,

I've never tried this before, so it's up to you to experiment ...

The model is just stored in a database.  Maybe you could do a search and replace through the back door, instead of doing it via EA.

General Board / Problems with forum login
« on: December 08, 2004, 07:54:33 am »
G'day folks,

I've noticed over the past week or so that my forum login, although set to last 600 minutes, will get disrupted/terminated/lost repeatedly throughout the day.

Anybody else having problems?

G'day,

I think what you see in the EA user guide are two partitions, side by side, each having their own label.
