Title: searching for a tutorial, or some samples(examples
Post by: tonywacu on May 12, 2010, 07:47:48 pm

Hello,

i m a big beginner on EA. My entreprise wants me to use it, to analyse all things that EA  can enable me to do as we are at the beginning of a project. Does someone has a tutorial or some application samples for me?
Please i need this.

Thanks you in advance   :)

yours,

Tony,

There is an example model delivered together with the install of EA.
Doesn't that satisfy your needs?

thanks you for the cases, they helped me to understand  how to model some issues.....

But at this moment i m modelling "business entities"(entité metier in fr)
and i don't know how EA deals with doubloons(doublon). After modelling i wish generate  DDL scripts

for e.G

diagram1(entity1----association---->::entity2,...)
diagram2(entity2--association-->::entity1,...)

i don t know if it s clear, but i can develop if you want.

thanks in ad

Tony,

Although I speak and understand french, its not clear to me what you mean by doublon.
The only thing I see from your example is a circular reference between entity1 and entity2.
In general circular references are a bad practice, but for DDL generation that shouldn't really be an issue.
The direction of the association is not relevant for the database layout, only the multiplicities between entities really matter to know where it should put a foreign key, or whether it should create a link table.

lool.... i m very bad in english!!!!

yeah this is going to help me!!!!
i was wondering if during the generation of the DDL, i would have two "tables" of the same thing. e.g:tableentity1 and another tableentity1
but with different "references".

am not sure for being clear again. sorry

Tony,

That doesn't depend on how many diagrams you have, but on the actual classes in your project browser.
If your entity1 is one class, but shown on two different diagrams then you should be fine.
If you have two classes with the name entity1 in your model, then you probably need to clean up the model first.
