The next series of chapters in the book will be built around a single project from several different perspectives. A real-world data source with earthquake information about the planet we live on will be tracked, recorded and displayed.

It is quite ambitious and there will be a lot of Dart along the way. It is surprising how much activity there is in the Earth's crust—perhaps you could blog or write a presentation on seismology using the output of our projects so far!

The project for this section is called QuakeMonitorFS—make sure that you select the project with the name ending FS and not DB. The FS version saves to the filesystem while the DB version saves to the database. We will first look at the filesystem storage version, and then move on to the database version.
