Introduction

Data is like food for applications; without it, they would have no meaning. Furthermore, data must be persisted; storing data can be done on the client, server, or both. On the client side, we look at IndexedDB and the Lawndart data manager, which provides offline data storage without having to worry whether IndexedDB is supported or not. Then, we investigate how to store data on the server in SQL as well as NoSQL database systems. By the end of this chapter, you will have a whole spectrum of choices to select the database in which you will store your app's data.
