many-to-many-relations

[Börries Ludwig]

Hi,

I am new to this list, but I did not find this questions, only one about "relations".

My question is simple: does Osage support many-to-many relations ?

E.g.:

public class Url{
private String url= null;   
private Vector keywords    =new Vector();}

public class Keyword {
private String keyword = null;
private Vector urls = new Vector();}

maps to following database-tables:

create table url (
Url CHAR(120) NOT NULL,
Uid CHAR(22) NOT NULL,
);

create unique index url_ui on url (Url);

create table urlkeyword (
Url CHAR(22) NOT NULL,   
Keyword CHAR(22) NOT NULL);

create table keyword (
Uid CHAR(22) NOT NULL,
Keyword    CHAR(40) NOT NULL);)

I could not get this simple example to run. I could only find onetoone examples.

Another minor question is, does Osage runs in VisualAge 3.5 ?

Help is very welcome

Hi,

There's no support for many-to-many.

You can find support for this in castor at castor.exolab.org.  I recommend using castor as I'm not now doing any work on osage, and castor has more features.
