There are many different kinds of persistent storage that Cordova apps can use. Which storage mechanism you use depends largely upon the storage needs of your application. Furthermore, your app isn't restricted to a single type of storage. It might make the most sense to store user preferences in localStorage
and larger files using the File API. On the other hand, neither localStorage
nor the File API provides a simple mechanism for storing, retrieving, and searching structured data. You can use them for these purposes, of course, but you'll have to do most of the hard work yourself.Two storage mechanisms come to our rescue so that we don't have to reinvent the wheel. The older (and now deprecated) standard, Web SQL Database, uses a relational data model typical of databases such as Oracle, PostgreSQL, Microsoft SQL, and so on.

Overview of this book
PhoneGap is a useful and flexible tool that enables you to create complex hybrid applications for mobile platforms. In addition to the core technology, there is a large and vibrant community that creates third-party plugins that can take your app to the next level.
This book will guide you through the process of creating a complex data-driven hybrid mobile application using PhoneGap, web technologies, and third-party plugins.
A good foundation is critical, so you will learn how to create a useful workflow to make development easier. From there, the next version of JavaScript (ES6) and the CSS pre-processor SASS are introduced as a way to simplify creating the look of the mobile application. Responsive design techniques are also covered, including the flexbox layout module. As many apps are data-driven, you'll build an application throughout the course of the book that relies upon IndexedDB and SQLite. You'll also download additional content and address how to handle in-app purchases. Furthermore, you’ll build your own customized plugins for your particular use case. When the app is complete, the book will guide you through the steps necessary to submit your app to the Google Play and Apple iTunes stores.
