General Board / Re: Feature for spacing diagram items
« on: August 04, 2003, 07:54:31 am »
Thanks Mikkel.

I hadn't been using the "multiple selection" element context menu. It seems a bit strange that the same function isn't available from the "diagram" main menu near the "Align" items.

General Board / Feature for spacing diagram items
« on: August 02, 2003, 01:45:17 pm »
There are tools for aligning and sizing items in EA diagrams, but I can't find one to help space out a column or row if items.

Ideally, a selection of items could be spaced out equally between the first and last items creating a neat column or row. This would be used where the auto layout features aren't suitable.

General Board / Relative Paths to Associated Files
« on: August 02, 2003, 02:10:24 pm »
Is there support for relative paths to files associated with model elements?

All the examples seem to show absolute paths which would break if a model and associated files were relocated to another storage location (e.g., if sent somewhere for review).

This could apply to "local files", and to "web addresses"  which could benefit from relative format with related "base URL". All of this would help with publishing models.

General Board / RTF Report Margins vs. Page Setup
« on: August 02, 2003, 01:32:32 pm »
The margins that show up in RTF reports are not the same as set in Page Setup. In my case, it means that diagram images are cut off where they extend beyond the report margin.

Is there a setting for RTF report margins that I missed finding, or should they end up the same as page setup (indicating a possible EA problem)?

General Board / Displaying Stereotype Indicators
« on: July 10, 2003, 07:34:28 am »
Is it possible to force the displaying of <<stereotype>> indicators in all diagram elements?

In cases where there is a special graphic form (e.g., the "process" stereotype) the text indicator "<<--->>" doesn't seem to be displayed.

So far, I haven't found a setting to control this.

Uml Process / Re: Aggregation overload! - in domain model
« on: March 26, 2004, 08:44:08 am »
These are clear and useful explanations, but I can think of two aspects that might be too narrow a view...

1. In modeling, you can think of what the data "is", or what the data is "about". There is a difference between a data item that is composed of other data items, and a domain object that is composed of other domain objects. The data items may be assembled in ways that don't necessarily parallel the domain.

2. When considering history and traceability, deletion of domain objects doesn't necessarily delete the parts, just the relationship between those parts and the whole. An engine might be traced (even given identity with an OID) from manufacture, then assembled into an identifable truck, then removed, reworked, and made available for use in another and different truck. In certain domains keeping traceability of the parts, and even the batches of material used to form them, is critical (e.g., medical implants, nuclear power plants etc.). As more organizations seriously consider having continuous improvement programs, and data-driven decision making, there is an even greater call for building history and traceability into the models and data systems.

Uml Process / Set Element Classifier missing Base Types
« on: August 11, 2003, 02:17:52 pm »
The choice list of available Base Types for "Set Instance [or Element] Classifier" doesn't include ENTITY.

It does include Actor, Class, Component, Interface, and Node. It would be very useful for Business Modeling to have "entity" included, given that it should parallel the use of "actor". Further strangeness is that ENTITY can aggregate but not generalize, while ACTOR can do both. ENTITY should also do both.

Of course there is some ambiguity in this because there is also an "entity" stereotype for object (base type) available. It would be best to use the ENTITY base type as the classifier for an "object" for clarity in business modeling.

Is there a table or database settings where these options can be controlled?

Uml Process / Stereotypes Table has unlisted Base Types
« on: August 11, 2003, 02:27:28 pm »
The database table "t_stereotypes" includes several "applies to" base types of Class and Connection that don't show in the available modeling elements. Also there are some modeling elements that don't show with stereotypes in the table "applies to" column.

For example, there are "business class", "business model" and "objectflow" in the table, but missing as elements. And "entity" is available for modeling but doesn't show in the table "applies to" column.

I imagine that the "applies to" column must agree via internal database constraints with the programmed base types.

Is there any way to change the base types for correcting the table?

Automation Interface, Add-Ins and Tools / Tangible Architect
« on: February 26, 2005, 05:08:24 am »
Is anyone using Tangible Arthitect with EA? Is it effective for creating the database schema and tiered system? What are your experiences? The Tangible site has been quiet for a while, no updates or traffic. Just wondering if it is viable.
