Linked Data (LD) is a well-established standard for publishing and managing structured information on the Web, gathering and bridging together knowledge from different scientific and commercial domains. The development of Linked Data Visualization techniques and tools has been followed as the primary means for the analysis of this vast amount of information by data scientists, domain experts, business users, and citizens. This book covers a wide spectrum of visualization issues, providing an overview of the recent advances in this area, focusing on techniques, tools, and use cases of visualization and visual analysis of LD. It presents the basic concepts related to data visualization and the LD technologies, the techniques employed for data visualization based on the characteristics of data techniques for Big Data visualization, use tools and use cases in the LD context, and finally a thorough assessment of the usability of these tools under different scenarios. The purpose of this book is to offer a complete guide to the evolution of LD visualization for interested readers from any background and to empower them to get started with the visual analysis of such data. This book can serve as a course textbook or a primer for all those interested in LD and data visualization.

The success of app stores has put dollar signs in the eyes of many app developers.

Aside from the potential payoff in terms of app sales, high profile acquisitions of app developers continue to make headlines.

If a single photo sharing app can go from zero downloads to millions of downloads, and eventually a billion dollar payday, so can yours. If a single drawing game app can go from zero downloads to a $200 million dollar payday, so can yours.

This book is a powerful resource that will help your app become famous, sell impressively, and succeed through fame.

PHP This! is a beginners book for developers who are new to object oriented PHP web development.

This goal of PHP This! is to teach the PHP skills needed to be a junior PHP developer. These skills include an introduction to object oriented PHP theory and instruction on how to apply that theory to build a full custom MVC application, unit testing with PHPUnit and code management with SVN.

The instruction provided by this book also applies to experienced software engineers with expertise in other languages who have not had the opportunity yet to learn object oriented PHP or to those who are new to web development altogether.

Object Oriented concepts can be confusing at first that is why PHP This! provides a simple way to explain a confusing subject. The clear explanations and examples will quickly teach you what Object Oriented PHP is and how to use it, test it and manage it. Some key chapters and subjects include:

In today's high-tech, information driven world, the security of personal data is vital. We have all heard the horror stories of personal data being compromised from companies, both large and small.

The data access framework that we will develop in Coding Briefs will allow us to create datasets, execute queries, and select data in a secure, managed process.

This framework will provide a solid foundation for managing secure data access through stored procedures, allowing us to select, insert, update, and delete records from a SQL Server database. We will have access to parameterized queries and will develop an automated process for discovering stored procedure parameters.

The major areas that we will address in this brief are as follows:
-Discussing the Data Access Framework (DAL)
-Importing Libraries and Declaring Values
-Managing the Database Connections
-Selecting Records
-Manipulating Data
-Preparing the Select and Execute Methods
-Working with Parameters
-Testing the Data Access Framework

And, as a bonus, two complete sample applications have been added; one for Windows, and one in ASP .Net, that will test all of the features on the data access framework.
