Hi, I have some questions about OJB. There are three APIs that you can use: Persistence Broker, ODMG and JDO. Do you have to choose one of these APIs to use in your project, or is it normal to mix them and use the one that is most convenient at the moment?
What if the database in your application is running for some time and you want to change the definition of the class ir change the mapping. For example you want to add a Nationality field to a Person class. What will happen to the old persistent Person objects? Can you specify a default value for the old objects? Is it possible to map a List to a table in such a way that entry 1 to 5 is mapped to column 1 to 5 in a table? Thanks for any answers, Robert. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
