Hi Daniel,
I do not anticipate you will be out of business either, perhaps in five years you will have a bachelors degree in DBA and you will know how to create scripts to export and import data into a new database. If not, then with the new application you purchase. Someone associated with that software will create a new database for you, just as they did with this application.
I like to leave things like databases, report creation and fixing the air conditioning in my store, to people who are trained to do it :)
In five years let someone else worry about how to create a new database for their application, just make sure it's backed up and maintained.
If you like to experiment?
Please do.
In a test environment.
Taking scripts, delete statements or reports from the forums or the internet and applying them to your live store, is not safe.
When someone tells you they want 4 or 5 hundred dollars an hour to fix it, because it's broken and you can't run your business or do sales.
That's the worst case scenario my friend and it happens way too much.
Have a great week Daniel.
