Applications and software that power the web
Web applications and software provide the code that delivers web pages and content over the Internet. Modern pages are mostly active rather than static as they were in the early days of the Web. Languages like PHP, Perl, .NET and allow developers to create dynamic pages that can use SQL and other types of databases to deliver highly targeted content. Frameworks like jQuery allow for client side scripting helping to ease the burden on servers. Ajax applications provide for asynchronous applications that communicate with the server in the background to provide content in a sophisticated manner. The large variety of web applications can include everything from chat software to programs that compute celestial movements. Web-based software can also include applications used for server management, web security and website performance analysis. Many applications may operate on the server side, i.e., those written in Perl and similar scripts. Such software can generate dynamic content based on user actions.
Languages like PHP allow you to write code on web pages that access the server upon loading. Database applications offer efficient storage of user and other data. Relational databases like SQL allow the server to quickly access data to provide user-focused content. On the client side, web applications can check and validate forms, provide content based on user actions, and provide services that work entirely on the web browser. For example, a browser-based calculator can estimate Social Security benefits or mortage payments based on user input. Web applications handle everything from cookies to security tokens, and they are essential for creating competitive websites. New applications are continuously under development, and we should see exciting new innovations in the future. For example, new applications are concentrating on the increasing use of smart phones and other small mobile devices over the traditional desktop or laptop computer.read more
Consumers now use their mobile devices to find destinations like shops, restaurants and tourist spots, so developers must create software for the mobile Internet. Among the current trends in JAVA development is the use of the language for cloud computing. For example, enterprise websites are increasingly worried about scalability issues, and they are looking to the cloud for solutions to include the implementation of private clouds. New JAVA applications must take into account the security issues involved in cloud computing.read more
