Delight in Thinking

This topic is very luxurious, encompasses many of the current hot area of information technology terms, from Web2.0 to cloud computing, these terms constitute a bright Web world from the past into the future road map.

The life cycle network around the world is a stage of ten years, from the first generation Web experiences to Web2.0 about 10 years, 10 years, Web address of the person's interaction with the network problems, from Web1.0 Just read the network information to provide users the convenience to the development of Web2.0 to provide users with interactive access, from, Web is not just a media, but rather an information exchange platform to communicate with each other. In the Web2.0 environment, users do not just Web-readers, but also Web content providers and participants, today, Web2.0 basic Web has matured and become mainstream. Web2.0 site full of large networks, and nurture a large number of users, it can be said, Web2. Really fostered the rise of a virtual network society.

W eb2.0 A key feature is involved, that Web users can participate in Web content development. This is a surface feature, in this feature is the technical architecture behind the changes, Web1.0 is mainly a web form, but to the Web2.0, HTML is no longer a Web-based, but the application system, in particular, is called of the content management system (CMS) for Web applications, Web1.0 to Web2.0 development is from the Web Page to Web Application Development Changes.

This kind of structural change in technology has changed the basic properties of networks, Web is no longer an isolated site were linked through the network, but a variety of Web application integration, Web content into functional and integrating through a whole into a large system. In order to achieve this integration, need to be addressed in the Web environment, communications between systems, especially functions and data reuse problem, so gave birth to Web Service framework, such a service-oriented architecture to become a landmark structure Web2.0 . Therefore, from a technical architecture perspective, Web2.0 feature is that Web services Web Service.

W eb as a large distributed system requires not only open the Web Application services (Web applications), also need to be structured description of data. Only through a structured description of data, application systems can be understood, in other words, an effective distributed network applications need to have the machine can understand the data. If Web2.0 is built on open service architecture, then a new generation of networks will be built on the basis of a machine can understand the structured and interrelated with the data environment, once the data environment established, then the Web will enter a new era, this new Web environment, we can call Web3.0.

W eb3.0 to be addressed is a data representation, allows the machine to understand the data structure information, the data structure information is called the semantic information, which is the core of semantic networks need to address the problem, so the Semantic Web can be viewed as is Web3.0 start. Semantic Web has experienced a development from concept to reality the process, its technical architecture has become increasingly clear, that is of concern associated with the data (Linked Data). There are two basic points associated data that describe and connect. The machine descriptions and links to all services, machines can be achieved by describing the automatic discovery and validation, the link can support the machine automatically link.

We go back and look at web1.0, 1.0 conditions, the browser get information from the server directly displayed on the screen, do not know the meaning of information, web pages and link each other through hyperlinks, but the need to manually click the trigger, 2.0 by the machine to automatically aggregate all kinds of information, and to 3.0, the network in the data layer on the establishment of a link mechanism, the data structure information is well described with, and through the URI to ensure that the machine can automatically link to a variety of data, to achieve intelligent automation of information aggregation.

Then, cloud computing is not the natural effect?
