Use of Web 2.0 concepts in development of web applications

The web has travelled a long way from its first website created in 1990. With its continuous revolutionary development, new used concepts and modern technologies, it became an important part of our everyday life. The web is not just a static database with information anymore, but a tool for many business processes and ordinary daily tasks. This shift was already exposed in 2004, and from then the web has acquired a new term, exactly Web 2.0, which relates to the second generation of the web and has the following properties: dynamics, interactivity, interoperability, information connectivity, user-generated content and the ability for providing user participation. In this diploma thesis I presented the web in its second evolution phase and the use of its concepts at development of web applications. In the theoretic part I presented the meaning of the Web 2.0, circumstances of its appearance, critiques and its three key elements (RIA, SOA and social web). I also focused on the typical functionality of modern websites, representatives of Web 2.0 websites, key differences between Web 2.0 and its predecessor, key web technologies and on the potential future of the web. With the intention to support the theoretical part, I merged most of the presented Web 2.0 features and characteristic into development of a smaller web application. With this developed Web 2.0 application I demonstrated that a web application can be built in an easy and quick way by using modern web technologies and Web 2.0 concepts.
