Hi I have a Derby database with 10 tables and some data inside them.
Because I'm a software developer and have many customers with their own databases and their own data inside them. I have also one empty database for developing purposes on my own. Can I inherit the changes I made to my own database to my customers databases without touching data in them? e.g. If I add two columns (color & weight) to my table (vehicles) can this change to be inherited to all other databases with the same table but different data in them? Why I ask is: If I'm going to add more features to my software, which uses Derby database, and these features need database structural changes, how can I update my customer's old software versions without touching the data inside their databases. Just need to add few columns more and don't want to clear data inside database. -- Juho Tykkälä
