Overview of this book

The ability to use SQLite with iOS provides a great opportunity to build amazing apps. Apple's iOS SDK provides native support for SQLite databases. This combination offers the potential to create powerful, data-persistent applications. This book starts with the architecture of SQLite database and introduces you to concepts in SQL . You will find yourself equipped to design your own database system, administer it, and maintain it. Further, you will learn how to operate your SQLite databases smoothly using SQL commands. You will be able to extend the functionality of SQLite by using its vast arsenal of C API calls to build some interesting, exciting, new, and intelligent data-driven applications. Understand how Xcode, HTML5, and Phonegap can be used to build a cross-platform modern app which can benefit from all these technologies - all through creating a complete, customizable application skeleton that you can build on for your own apps.

Creating a database

To start, a database must be created. By using the following command to create the database, although it will be created, nothing will be physically stored in the database yet. There is no default place to store the SQLite database once it has been created. The location could be your home directory, a working directory, or a pre-created database directory:

$ sqlite3 testdatabase.db

By default, an environment is prepared ready effectively, for database objects, as defined by the preceding statement. SQLite was designed with the distinct policy of avoiding any size limits. To have a policy that would easily fit in the device's memory and be a 32-bit integer would work, but was not the best option. It proved to create problems since the product was pushed to extremes and the exploitation of security loopholes may have made the product vulnerable. The default settings of objects are generous and adequate for most applications. There are also different settings statements...
