Let's now take a look at the concrete example we will be working on for the remainder of the book. In our example, we work for an organization called Matangle. This organization is a software as a service (SaaS) provider that sells access to educational games for schoolchildren.
As with any such provider, we will, with all likelihood, have a database containing customer information. It is this database that we will start out with.
The organization's other systems will be fleshed out as we go along, but this initial system serves well for our purposes.
