Patterns ain't patterns

[Paolo F Cantoni]

With apologies to the the famous Castrol "Oils ain't oils" advert (Google/Bing it).

Am I correct in understanding that there are TWO types of patterns in EA?

• UML Patterns - used for generating clusters of inter-related items
  
• Model Patterns - used for generating package structures.
  

You typically use a Model pattern when you are creating a new package.

Both can exist in an MDG Technology.

TIA,
Paolo

Feels about right to me.

There is a new feature called re-usable asset library. Haven't had a chance to look into it but I get the impression you can use that to manage patterns too.

Yes, normally an RAL is essentially that.  However, we'll need to see how Sparx has implemented it exactly to confirm/deny.

As I understand it, Sparx's RAL relies on Cloud Services (which is one reason I'm investigating them at present) - or have I got that wrong?

No, I think you got that wrong.
AFAIK RAL just uses a another database on the same server.

Like doing queries over two databases that are hosted on the same database server.
But I've never tried it out for real yet.

You do require cloud services to be running to use the RAL feature.  The only access provided is through a http/https url not a regular database connection. The RAL is just another database, but it doesn't have to be on the same server or even a server at all.

I tested the setup with both a SQL server database acting as the RAL on the same server and using a firebird database accessible through a cloud service url (though I'd never implement that in a production environment).

[Geert Bellekens]

Yes indeed. I just looked at the actual manual (that helps sometimes  ) and I was completely wrong.

I don't know where I got that idea
