Chapter 4. It's All about the Data

In this chapter, we're going to learn about the use of the data package in Ext JS. Also, we will talk about Ajax, Data Models, Data Stores, and the available readers and writers that we can use in order to store our data locally.

It's important to have a solid understanding of the data package so we can link or bind data into Ext JS components. The data package contains multiple classes to handle data, but there are some main classes which will be used almost always. Take a look at the following figure:
