Define DataRelation

[aescot]

Good afternoon,

I am evaluating your software for maybe use it.

I have somes questions concerning data relations :

What is the best way to define data table relations ?

I try to declare relation like this :

Code: Select all

            ArrayList<String> parentColumn = new ArrayList<String>();
            parentColumn.add("IdSup");
            ArrayList<String> childColumn = new ArrayList<String>();
            childColumn.add("IdSup");
            StiDataRelation relation = new StiDataRelation("Support", "Support", "Support", tableSource2, tableSource1, childColumn, parentColumn);

But it is not easy to use with an Object Relational Mapping like Hibernate. Is there a btter way ?


Moreover, is the data file have to specify relation ?

Thanks for your helps and support.

Hello,

My question is very similar to this recent post http://forum.stimulsoft.com/viewtopic.php?f=19&t=38402 because I want to map your software to my entities bean which are used by hibernate.

In your demo application, you define your objects and relations using a xsd file. When I see a relation beetween two entities, it is not specify if it is a One to many or a many to one relation. Is it normal ?

And then, how can I construct a XML data file according to this relation ?
For exemple, If I have an object which contains another object (his relation for the report), how I have to send the data ?
Is it not possible to directly give the full object and bypassing the XML data file ?

Thanks for your help.

Regards,

Alex

Hello,

We will try to prepare the sample with using relations.

Our products support standard XML data, you can create them any available methods.

Thank you.

Thanks for your answer Aleksey, I am waiting to your sample.

Yes, I have seen that it is possible to give data using a XML file as in your demo application but it seems complicated to write it if there are many relations between objects.

It is that why I am fully interested if there is another way to send data like RegBusinessObject class in .NET which permit to give to your software the complete object.
Or maybe another way ?

Thanks for your help.
