One of the best ways to learn a new set of tools, like those that make up a programming language and environment, is to experiment with them. We're going to have some fun doing that throughout this book. We're going to experiment where the cost of errors (otherwise known as learning) is small. Our development work will be a custom application of Business Central for a relatively simple, but realistic, application.
We're going to do our work using the Cronus demo database that is available with all Business Central distributions and is installed by default when we install the Business Central demo system. The simplest way is to use the sandbox.
The Cronus database contains all of the Business Central objects and a small, but reasonably complete, set of data populated in most of the system's functional application areas. Our exercises will interface very slightly with the Cronus data, but will not depend on any specific data values already there.
