Introduction

DotNetNuke is a free, open-source evolution of Microsoft's celebrated ASP.NET reference implementation, the IBuySpy portal solution kit. DotNetNuke began life as a framework for constructing data-driven intranet and Internet portal applications, and has now developed into an advanced web content management system with tools to manage a dynamic and interactive data-driven website. The DotNetNuke portal framework allows you to quickly create a fully featured community-driven website, complete with standard modules, user registration, and integrated security. This free open-source application puts a staggering range of functionality into your hands, and, either by using it as is or by customizing it to your requirements, you are giving your projects a great head start.

Supported and tested by thousands of developers in the DotNetNuke community across the world, the DotNetNuke framework, on one hand, offers you the luxury of a well-tested and proven architecture, and on the other, the ability to manage your site through an easy web-based administration system.

The book is structured to help you understand, implement, and extend the DotNetNuke framework; it will take you inside DotNetNuke, allowing you to harness its power for easily creating your own websites.

Preface

Ruby on Rails is an open-source web application framework ideally suited to building business applications, accelerating and simplifying the creation of database-driven websites. It has been developed on the Ruby platform.

This book is a tutorial for creating a complete website with Ruby on Rails (RoR). It will teach you to develop database-backed web applications according to the Model-View-Controller pattern. It will take you on a joy ride right from installation to a complete dynamic website. All the applications discussed in this book will help you add exciting features to your website. This book will show you how to assemble RoR's features and leverage its power to design, develop, and deploy a fully featured website.

Preface

A web mashup is a new type of web application that uses data and services from one or more external sources to build entirely new and different web applications. Web mashups usually mash up data and services that are available on the

Internet—freely, commercially, or through other partnership agreements. The external sources that a mashup uses are known as mashup APIs.

This book shows you how to write web mashups using Ruby on Rails—the new web application development framework. The book has seven real-world projects—the format of each project is similar, with a statement of the project, discussion of the main protocols involved, an overview of the API, and then complete code for building the project. You will be led methodically through concrete steps to build the mashup, with asides to explain the theory behind the code.

Preface

Software Configuration Management (SCM) is one of the first skills a serious developer should master, after becoming proficient with his or her development tools of choice. Unfortunately this doesn't always happen because the subject of SCM is not commonly taught in academic or company training.

Although software is not a material thing, as you cannot touch it, smell it, or taste it, building software can be as complex as building physical things such as cars or planes, if not more so. The main difference between the two worlds lies in the limitations you confront. In the world of developing software there are no physical limitations—the only limit is your imagination.

However, all this freedom can have a downside. A good TV commercial once stated "Power is nothing without control"—if you do not control it wisely, it may start working against you. When developing software, you need to have a manageable team development effort, track and maintain the history of your projects, sustain parallel development on multiple product versions, fix bugs, and release service packs while further developing the applications.

This is where the concept of Software Configuration Management (SCM) comes into play, dealing among other things with source code versioning, tracking development evolution, building, and releasing. Putting it in simple terms, SCM is about getting the job done safer, faster, and better.

While trying to keep the theory to a minimum, this book starts by teaching you what SCM is, why it is important, and what benefits you get by using it, either by working individually or by being part of a team. You will find this part very valuable if you're new to the concept of SCM, because you will be setting your base for understanding what happens in the rest of the book.
