In the previous chapter, you learned about data persistence using files. For simple applications, you can write the data you want to persist to a simple text file. For more structured data, you can use a property list. For large and complex data, it is more efficient to store them using a database. The iPhone comes with the SQLite3 database library, which you can use to store your data. With your data stored in a database, your application can populate a Table view or store a large amount of data in a structured manner.
This chapter shows you how to use the embedded SQLite3 database in your applications.
