Hi

In the context of UML2, what is the most appropriate way to set certain properties within a class (possibly in other related classes) as business keys for a class?

kind regards,

Hi

It depends what you want to achieve.

If it's documentation use a Comment.

You need might fall within the capabilities of isId, else nested properties.

If you want sophisticated code generation you might want to use Stereotypes to identify your distinguished behaviours.

Is it also an appropriate option to use constraint defined in ocl?

Hi

You've given no clue as to what you mean by a business key, so all my replies are guesses.

OCL can be used for a variety of things, so you might use OCL to define your business logic, but I would have thought that using OCL to declare a business key would be a bit perverse.
