Web Development

Advantages of Web Applications Yes, there are lots of headaches when trying to deliver functionality via the Web. But why bother trying to do that in the first place, instead of building plain desktop applications? Well, even with the current problems that web applications have with being user-friendly, they have acquired extraordinary popularity because they offer a number of major technological advantages over desktop applications. • Web applications are easy and inexpensive to deliver. With web applications, a company can reduce the costs of the IT department that is in charge of installing the software on the users' machines. With web applications, all that users need is a computer with a working web browser and an Internet or intranet connection. • Web applications are easy and inexpensive to upgrade. Maintenance costs for software have always been significant. Because upgrading an existing piece of software is similar to installing a new one, the web applications' advantages mentioned above apply here as well. As soon as the application on the server machine is upgraded, everyone gets the new version. • Web applications have flexible requirements for the end users. Just have your web application installed on a server—any modern operating system will do—and you'll be able to use it over the Internet/Intranet on any Mac, Windows, or Linux machine and so on. If the application is properly built, it will run equally well on any modern web browser, such as Internet Explorer, Mozilla Firefox, Opera, or Safari. • Web applications make it easier to have a central data store. When you have several locations that need access to the same data, having all that data stored in one place is much easier than having separate databases in each location. This way you avoid potential data synchronization operations and lower security risks. In this book we'll further investigate how to use modern web technologies to build better web applications, to make the most out of the possibilities offered by the Web. But before getting into the details, let's take a short history lesson. 9
