David Wolber, Hal Abelson, Ellen Spertus and Liz Looney, “App Inventor”
O’R lly Me ia | 2011 | ISBN: 1449397484 | 384 pages | PDF + epub | 27,9 + 15,8 MB

Create mobile services and applications regardless of your computer programming knowledge. This extraordinary book introduces you to App Inventor for Android, a powerful tool that exposes you to the world of computer programming, so you can create technology rather than merely consume it.

You don’t need years of training to build your own Android apps. This book teaches you how to quickly design and code apps for anything from texting to location awareness to data storage on the Web, using App Inventor’s unique visual interface. Ideal for beginning and intermediate Android developers, hobbyists and makers, and students of any age, App Inventor will help you turn your great idea into a full-functioning app in no time.
Take advantage of App Inventor’s GPS-location sensor: Build an app shows the location of friends or colleagues at a concert or conference, or one that gives you a custom tour of your school, workplace, or a museum.

Use an Android device’s phone features: Write an app that periodically texts “missing you” to loved ones, an app that responds to texts automatically when you’re driving, and an app that reads incoming texts aloud.

Communicate with the Web: Create Android apps that talk to your favorite web sites, such as Amazon and Twitter.

Joel Murach, “Murach’s Oracle SQL and PL/SQL”
Mi e Mur ch & As ociates | 2008 | ISBN: 1890774502 | 600 pages | PDF | 85,3 MB

If you’re developing applications that access Oracle databases, you can save time and work by having SQL do more of the data handling for you: This new book shows you how. It teaches you how to create effective SQL queries to extract and update the data in an Oracle database. It teaches you how to design and implement a database, giving you insight into performance and security issues. It teaches you how to use PL/SQL to take advantage of powerful features like stored procedures, functions, and triggers. In short, it teaches you to create the kind of efficient database applications that make you a more effective and valuable developer.

Here are 5 of the ways that our book differs from the others

#1: You’ll see how to take advantage of the Oracle SQL Developer tool
SQL Developer is a free tool for working with database objects and SQL statements. Its graphical interface makes it more intuitive and easier to use than older command-line tools like SQL*Plus. I think you ll find it boosts your productivity as you use it to write and run queries, to work with database objects, or to debug stored procedures.

#2: You’ll start off with how to query a database, not how to design one
This book is written for application developers, and the first thing an application developer needs to know is how to write queries. So that’s what’s covered in the first 8 chapters of this book. It starts with simple queries, then moves on to complex inner and outer joins, summary queries, and subqueries that do more of the database processing so that your applications can do less.
Once you’re comfortable with querying databases, this book shows how to design a database and how to create database tables. Having this background can help you query a database more effectively. And it provides a solid introduction to DBA skills if you’re interested in that career path.

#3: You get 2 books in 1: A SQL book and a PL/SQL book
PL/SQL allows you to write complex scripts, stored procedures, functions, and triggers, all essential skills for most application developers. So along with SQL, this book covers the PL/SQL that you’ll use most of the time; there’s no need to buy a second book to learn PL/SQL.

#4: Complete applications show you how all the pieces interact
One key to mastering SQL is to have plenty of coding examples that show how the features you re learning work and what problems you may run into as you use them on your own. So this book provides dozens of SQL statements and PL/SQL scripts for various jobs that are routine in business applications. Download the examples for free from our website and use them as starting points for your own SQL routines.

#5: The paired-pages format lets you set your own pace
Depending on what you already know about Oracle SQL and how fast you want to go, you can read every page and study each example…skim through the headings for topics you don’t know…scan through the righthand pages for development details you might have missed in the past…or turn to any two-page spread when you need reference information. The paired-pages format makes it easy and fast for you to use the book the way you want to.

(If you aren’t familiar with how the paired pages work, please be sure to download a sample chapter from our website)

Joel Murach, Andrea Steelman, “Murach’s Java SE 6: Training & Reference”
M.ke M..ach & Ass..tes Inc | 20o7 | ISBN: 1890774421 | 832 pages | PDF | 125 MB

This book teaches how to develop Java applications at the professional level. It starts by showing how to code, test, and debug everyday business applications that won t crash. It presents object-oriented features like classes, inheritance, interfaces, and polymorphism in a way that s both understandable and useful in the real world…perspective that s often missing in Java training. It presents essential Java skills such as working with data types, control statements, arrays, collections, generics, enumerations, exceptions, threads, Swing components, applets, and text and binary files. It covers new Java SE 6 features such as new JDBC features, the StAX XML API, and the built-in Derby database. And it s all done in the distinctive Murach style that has been training professional programmers for more than 30 years.
From the Publisher

Developers often tell me they wish they’d found our Java book first, before spending time and money on others. Here are 4 of the reasons why I believe this book will work equally well for you:

#1: The first six chapters get you off to a fast start
By the time you complete these chapters, you’ll be writing bulletproof, object-oriented applications with business classes and objects. These chapters work well for the complete beginner. But they also get the experienced developer up-to-speed fast.

#2: The class summaries help you master the Java API and save you hours of research
Although most books present dozens of coding examples that illustrate the use of some Java classes, they don’t try to summarize all of the classes, constructors, and methods that you’ll use the most. Our book does both. For instance, to learn how to use the LinkedList class, you’ll first see a summary of its primary constructors and methods. Then, you’ll see coding examples that show you how you can apply those constructors and methods. This can save you hundreds of hours of research over the course of the book.

#3: Chapters 7 and 8 show you how to use inheritance, interfaces, and polymorphism in a way that is both practical and understandable
You won’t find any toy applications or cat and dog objects in these chapters. Instead, you’ll study practical examples that show you how to use inheritance, polymorphism, interfaces, type-safe enumerations, and the factory pattern in business applications. This at last takes the mystery out of object-oriented programming. And we just haven’t seen this done right in any other book.

#4: The paired-pages format lets you set your own pace
Murach books have a distinctive format, where each two-page spread presents a single topic. Both beginning and experienced developers find that this format makes it easy to focus on the information they need, whether they’re using the book for training or reference. To see how this works, you can download sample chapters for free from the Murach web site.
