This document discusses the key concepts and components of Web 2.0. It describes Web 2.0 as aiming to enhance creativity, information sharing, collaboration and functionality of the web through characteristics like rich user experience, user participation, and dynamic content. It identifies Rich Internet Applications (RIAs) created using technologies like AJAX as enabling delivery of rich content to large audiences. RIA frameworks mentioned include Adobe Flash, Flex, and others. Service-oriented architecture (SOA) is also discussed as a way to develop software using reusable services with well-defined interfaces.

10. SOAEssentially, SOA is a better way to develop software, by using the basic building blocks of "services." Services are self-contained, stateless business functions, each of which accepts requests and returns responses through a well-defined, standard interface.Key Benefits A key benefit to using an SOA solution is that the different components can be developed by different teams that have nothing in common but provide and use a specific and agreed upon protocol for communication between components.

11. There are many benefits to developing an SOA solution, such has dividing the workload of development to different teams or even different companies, providing a way to share the development costs with partners and/or vendors.Web 2.0
