In this chapter, we will be working with SQL databases. While you will not be required to write your own queries, having a basic understanding of SQL (in particular, the SQLite 3 variant) will help you to understand the queries that are used.
This chapter also assumes that you have successfully gotten Qt running on your target, and that you have been updating your BigProject along with this book. This chapter builds more features into BigProject. The source code for the examples and projects in this chapter, including this chapter's end implementation of BigProject, are available at https://github.com/PacktPublishing/Hands-On-Embedded-Programming-with-Qt/tree/master/Chapter07
