Dynamic and Interactive Web Application Explained
The poster ask question with the following information :
Could anybody could tell me what “dynamism in web applications” means to them? I’m trying to develop a web application for my 4th year thesis that will incorporate dynamism and interactivity. I was hoping to develop something using HTML5 and CSS3 with HTML5 APIs showcasing interactivity.
When I think of dynamism I think of techniques such as AJAX & JSON and their implementation within a 3 tier client/server architecture but I’m not sure whether or not I’m missing something.
Dynamic and Interactive are two separate words:
- Dynamic is a state of change. It is best represent by a back-end.
- Interactive is an action that produces a result. It represent the front-end.
Naturally, the two of them goes together.
Now, onto back-end and front-end :
- The back end represent processing that are done behind the screen, without the user aware of the process.
- The front end, is of course what the user see on the screen and ‘interact’ with.
So, the back end is usually a web programming language, which can be anything from PHP, Python, Ruby, ASP and a lot of other web programming languages. The back end also contains a database, which can be standard SQL-based databases such as MySQL, PostgreSQL, Oracle, MS SQL, etc. Or it can be a NoSQL-based databases.
The major point is that the back end is a storage with interface done by a web programming language.
The front end is also the face of the application, because the user mainly interacts with it.
How do front-end and back-end communicates ? Normally through HTTP protocol of GET and POST. They can also communicates via REST, implemented through JSON.
There have been a lot of progress made to unify the front-end and back-end. Such as HTML5 storage. However, the main resistance is that browser based interaction should be confined to a sandbox mode. This is to prevent a major failure on the server (back-end) due to incorrect programming on the front end, as well as for security reason.
Now, I hoped I cleared the true meaning of dynamic and interactive in web applications. Hope you find them useful. Feel free to share your thoughts in the comment section below.
