Hi, I'm evaluating possibility on using an O-R mapping tool in my current project. I've read tutorial on torque and similar other O-R mapping tools and wonder how the migration is managed.
Suppose, I've created a book database scheme, generate sql/java code and deploy it. Some time later when a lot of data 's been filled into DB I discovered that I had to add/change/remove some properties on the Book class. I could tweak the schema file and re-create sql/java code but how one typically perform migration data to new db scheme. An elaborate answer or pointers to relevant Web resources are greatly appreciated. -- Regards, max. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
