Sencha Ext JS is an industry leader for business-standard web application development. Ext JS is a leading JavaScript framework that comes with a myriad of components, APIs, and extensive documentation that you can harness to build powerful and interactive applications. Using Ext JS, you can quickly develop rich desktop web applications that are compatible with all major browsers.
This book will enable you to build databases using information from an existing database with Ext JS. It covers the MVC application architecture that enables development teams to work independently on one project. Additionally, the book teaches advanced charting capability, enabling developers to create state-of-the-art charts just once. These charts are compatible with major browsers without the need to rely on plugins.
This hands-on, practical guide will take you through the mechanics of building an application. In this instance, we will use this application to manage existing data structures in the form of a database.
You will begin by making SQL and tables in MySQL and will then move on to developing the project environment and introducing Sencha Cmd. You will learn to create a form to input data and monitor the state of the input, while seeing how Ext Direct will validate the form on the server side.
Finally, you will have a working application that is ready for you to customize to suit your needs. You can also use it as a template for any future projects when you need a similar database.

Foreword
Ext JS Data-driven Application Design, by Kazuhiro Kotsutsumi, is a practical hands-on guide for both intermediate and expert JavaScript developers using Sencha's Ext JS 4.x framework.
This book is aimed at developers who not only want to learn how to develop a real-life desktop application that can read from and write to a database, but also want to see how to use the framework's advanced features they might not yet have heard of.
Kazuhiro begins describing the application development process by leading the reader through the database structure that the application will be using.
He continues by laying out the application structure using the MCV (model-view-controller) pattern—decoupling the UI, data, and business-logic—while detailing how to use Sencha's CLI tool Sencha CMD (Sencha Command) to help in that process.
He utilizes the framework's power by showing the reader how to use the advanced feature Ext Direct, describing in detail and with code examples what it is, how to add it, and how to use it in an application. He also brings in browser history support and again points out clearly how and why it can be used in an application.
Finally, after describing how to add and read database entries into the application and back to the server, he finishes his book explaining how to visualize the data in different charts and importing to or exporting from the database.
By using the carefully described features introduced in this book, you too can use this great architecture to build your own future applications.

Preface
Ext JS is a leading JavaScript framework that comes with a wealth of components, APIs, and extensive documentation that you can harness to build powerful and interactive desktop applications. By using Ext JS, you also quickly develop rich desktop web applications that are compatible with all major browsers. This book will take you step-by-step through building a clear and user-friendly sales database in Ext JS using information from an existing database.
Rather than just explaining MVC, this book is a hands-on, practical guide that will take you through the mechanics of building an application. By the end of the book you will have a working application that is ready to customize. You can also use the architecture from this book in future projects to simplify controls, improve maintenance, and expand applications with ease.
You should be able to grasp the idea of the example data structure introduced in this book. This book has been written on the premise that you are familiar with JavaScript and have basic operational knowledge of MySQL.
What this book covers
Chapter 1, Data Structure, focuses on preparing the basic foundations of your database. It will deal with an existing virtual company's data structure and the making of SQL and tables in MySQL.
Chapter 2, Planning Application Design, develops the environment of the project, while at the same time introducing Sencha Cmd. You will learn to design a simple application and optimize Ajax requests in order to use Ext Direct and Ext.util.History to control the screen with a URL.
Chapter 3, Data Input, discusses making a form to input data, then transmit that data to a server via Ext Direct. You will also learn to monitor the state of the input and how Ext Direct will validate it on the server side.
Chapter 4, ListandSearch, speaks mainly about displaying data that we read in Chapter 3, Data Input. However, users will no doubt want to search the data, so this chapter will also introduce data searches.
Chapter 5, Reporting, focuses on the implementation of the report displaying it with four different types of graphs on the dashboard.
Chapter 6, Data Management, focuses on the implementation of data import/export, done to restore or to keep a backup of the data.
