IWST 8. Data acquisition from the server. Design of the graphic interface Web applications. Creation of styles.

            Purpose: The manual focuses on modern methods of design and development of web-applications. It explains the concepts and basic Internet standards and sold to its web-based network (World Wide Web), the composition of the network software works web-based application logic, the main approaches and the development of technology.

Introduction

            A Web application (Web app) is an application program that is stored on a remote server and delivered over the Internet through a browser interface. Web application - In computing, a web application or web app is a client–server software application in which the client (or user interface) runs in a web browser.^[1] Common web applications include webmail, online retail sales, online auctions, wikis, instant messaging services and many other functions.

Through Java, JavaScript, DHTML, Flash, Silverlight and other technologies, application-specific methods such as drawing on the screen, playing audio, and access to the keyboard and mouse are all possible. Many services have worked to combine all of these into a more familiar interface that adopts the appearance of an operating system. General purpose techniques such as drag and drop are also supported by these technologies. Web developers often use client-side scripting to add functionality, especially to create an interactive experience that does not require page reloading. Recently, technologies have been developed to coordinate client-side scripting with server-side technologies such as ASP.NET, J2EE, Perl/Plack and PHP.

Ajax, a web development technique using a combination of various technologies, is an example of technology which creates a more interactive experience.

Writing a web application is often simplified by open source software. These frameworks facilitate rapid application development by allowing a development team to focus on the parts of their application which are unique to their goals without having to resolve common development issues such as user management. While many of these frameworks are open source, this is by no means a requirement.
