When we were kids, the sandbox was the place you could play, and build things, and knock them down and create new things. It was a place where taking chance was encouraged because there was no real risk of doing something “bad.”
In databases, the sandbox environment is a place where you can play, and test, and try new things, all without the risk of doing something “bad.”
Do you have a “sandbox” environment where you can play with your database, its data, and its functionality, without risking doing any really harm? I’m amazed at how often I encounter associations who do testing and training within their live environment.
It’s too risky to do this, and a sandbox environment is a cheap (sometimes FREE) way to ensure you don’t do serious damage to your real data or database.
If you don’t have a sandbox now, ask your vendor how you can get one.
