Hi,

I have a class like

public class EligibilityRules {

long id;

Set certifications; // set of name value pairs

Set specializations; // set of name value pairs

Set authorizations; // set of name value pairs

...
...
// 10 more collections like the above

}

The straight-forward way is to map each collection to a separate physical table. However, there can be potentially more and more. Is there any way of mapping all the collections to the same table with a composite key made of id and some text representing the field ? What would the mapping look like ? Any ideas of how this can be done ?

Thanks,
ramky
