Views properites
« on: August 15, 2007, 02:41:38 am »
Hi
I created a view in data model diagram (1st time I use it) and when I tried to rename it I discovered I can't enter normal objects properties.
I had to rename it through the diagram it self.
It might be me, but I don't understand why a view wouldn't have normal properties, I found it some what "surprising"

It's probably because Views are not meant to have any attributes on their own.

Notes? scenarios? requirements?
And I'm sure I'm missing others...
Why shouldn't it have such assets?

Because it's BAD - Broken as Designed.  ???

You can get some of these "properties" back...  You can drag and drop attributes (as columns) from the various tables onto the View (or use the browser).  AND... (at special request from us) these columns should NOT appear in the generated view - they're for information only (at present).

You can also, temporarily, change the stereotype (to nothing) via the properties window and add the missing bits (responsibilities, constraints and others) and they'll remain when you change the stereotype back...

HTH,

No so Thomas...

Both from a theoretical and practical perspective.

Each column (attribute) in a view is a derived item, but it is real none the less.   The properties attached to the derived item may be quite different to the properties of the source item(s).  In addition, you need to have a place to store the access function of the column.

This is all possible in fully-fledged Database Modelling tools such as Embarcadero ER/Studio.  The current Sparx implementation (which is better than having NO view capability at all) can ONLY be seen as a minimal interim solution.  You aren't actually "modelling" views with the current implementation.

Not only do they remain - and can displayed on the diagram, BUT (wait! There's more!) thanks to EA's Unique interface - you can select one of these additional compartments and then double-click the selected compartment to bring up the usual (and now unavailable) dialog and tabs!  So you don't have to keep changing the stereotype!

NOTE: THIS IS NOT A FEATURE!  IT'S BEING FORCED TO USE (TAKE ADVANTAGE OF) THE INCONSISTENT INTERFACE TO ACHIEVE WHAT SHOULD HAVE BEEN THERE IN THE FIRST PLACE...   ???

Sorrt, I found no way to change the stereotype, since I have not such info in properties!
I guess it might be possible to do it through diagram, but it is annoying...
I still need to try Paolos' solution though.

Hi Martin,

The Properties Window comes up with View|Properties     Alt + 1.  You can change the stereotype there...

This trick [size=10](changing inaccessible stereotypes via the Properties Window)[/size] allows you to circumvent MANY questionable EA UI (Unique Interface) restrictions...

HTH,
Paolo

You're defintely right. It was more like finding an explanation why Sparx did it this way....
