Web 2.0 applications are modular , with developers and users able to pick and choose from a set of interoperating components in order to build something that meets their needs. Not only that but the Web 2.0 applications themselves become components for building yet more applications. Web 2.0 applications will return to users control of their information. Web 2.0 applications aim to interconnect users and contents so that users can use contents to find participants and vice versa. Resource description language (RDF), a language for Web 2.0, targets to represent information semantically and exchange knowledge in the current Web environment.

Web 2.0 applications are responsive, have rich user interfaces and involve user participation in some way, often by allowing for user input and tagging of content. This is quite different to traditional or Web 1.0 applications. Web 2.0 applications have collaboration and data from the Web on their side, but desktop applications have strengths, too. Chief among these are an operating environment and a user interface built for single-person interaction and a rich feature set based on many years of development. Web 2.0 applications must also evolve quickly to meet users? Moreover, a rapid application development environment is essential for a development team to keep up with these demands.

AJAX as a technology has a high technical barrier to entry because it requires programmers who are fairly skilled at XML, normal server-side application design, and Javascript programming at once. Moreover, browser support for AJAX varies, there are no relevant international standards, and tooling support is currently poor but rapidly improving. Ajax is considered a central part of the new Web 2.0 trend, and for doing Ajax, the author recommends Scriptaculous, which is based on Prototype — both introduced in Chapter 5. The basic CSS styling of the sample application’s Web pages, is covered in Chapter 6. Ajax frameworks, providing new avenues of attack and compromising confidential information. Written for intermediate-to-advanced security professionals and developers, the book explores Web 2.0 hacking methods and helps in enhancing next generation security controls for better application security posture.

Server Intellect’s support is top notch and for one price, they provide the most reliable hosting we’ve ever had. Servers can be in multiple datacenters in case one datacenter is not accessible. If the application requires a database on the local network, the other datacenter can still be used as a backup in case your primary one is unavailable.

Note that there are two links for each widget. The first one is using JSP tag while the 2nd link uses JSF tag. Note that Sharepoint implementations are relatively costly, as they involve hardware (Sharepoint doesn’t run as a SAAS), licensing fees (for Sharepoint and SQL Server), configuration and training costs.
