What makes application framework a popular choice for Web programmers
?
The World Wide Web is becoming dynamic and multi-functional over the years. Users are hungry for advanced and sophisticated web-based applications, that too on a customizable platform. It seems web-integration and maintaining web-application needs to be revamped. Gen Y demands interactive, multi-optional and real-time intelligent solutions.
Challenge for the web specialists:
What does this change indicate to web-programmers and developers of 21st century? How to deal with the most complex of web applications? How to incorporate versatile social networking features; create powerful and secure applications on existing web-media? Not to mention "Web is becoming small, compact and more user-oriented".
Application framework the unique solution
To support all these tasks, such as - development of dynamic websites, web-applications and latest web services, you need a dependable software framework, that is, "Web application framework" that helps streamlining common web development activities and debug the process overheads.
The web application framework comes with a number of services, such as creating libraries for database access, session management, templating frameworks and reusing codes etc. All these are designed to interface external applications with web servers.
Whether it is to integrate top class interactive features into a website or building a highly competent online search tools or incorporating multi-media services into your commercial web platform web application framework is the one stop solution for all.
Symfony- an open source application framework
One such popular web application framework is "Symfony"- a free software which has been released under the MIT license. It is written in PHP (a scripting language that helps designing dynamic web pages). Symfony uses Model-View-Controller (MVC) a software architecture that separates application logic for the user from the user interface. The benefit with this architecture is that it uses 3 triads- Model, View and Controller which allows independent development, testing and maintenance of each distinct feature.
Most of the web application frameworks are based on MVC architecture. However, earlier, some projects used content management system as framework architecture. For example, Drupal development could provide extendable architecture and customizable modules to build sophisticated web applications.
However, before you get into the real-world usage of Symfony development, it is imperative to know the evolution of web application framework.
How did application framework originate?
Earlier the design of WWW was static. Those days programmers used to hand-code the HTML and publish it on web server. Only page author was permitted to do modifications on published pages. It was tiring and insufficient.
However, Common Gateway Interface (CGI) standard came in place to establish to interface external applications with the web servers. But, it affected server load as each request needed to start a distinct process.
Eventually programmers needed tighter integration with the web server to enable high traffic web applications. There were introduction of HTTP Apace server, Apache Tomcat web server to facilitate arbitrary code executions, handling dynamic web content etc. Even new languages were developed like PHP, Cold Fusion etc.
Finally, full web application framework appeared. This gave rise to a cohesive single software stack (libraries) for the web developers to use.
It's still improving. The upcoming version of application frameworks are releasing with new features.
Commercial use of Symfony- the application framework:
1. Web developers use symphony based application to fasten the creation and maintenance of web applications and avoid repetitive coding job.
2. It builds robust applications in an enterprise context, thus provides developers full liberty to control over the configuration - right from directory structure to the foreign libraries everything.
3. Symfony is provided with extensive debug and documentation tool. It can also correlate various relational databases.
4. Open source Question & Answer Service and many more social networking applications like Delicious; use Symfony for their computer program.
5. Many commercial websites do implement Symfony based application features on their websites. Whether it is travel or hotel planning and booking website or online audio-video sharing system Symfony create every critical user application with external servers.
Thus Symfony has become the backbone of any type of advanced web application be it for a social network or ERP system anything.
