Everything in this world goes through certain phases. Human beings also have different stages in their lives. This is what we call life cycle. It is no exception that software applications and programs follow a development life cycle. This is referred as Software Development Life Cycle or SDLC. This concept is coined during 1970s as a medium to build software. The chief objective of this life cycle is to develop applications that fulfill the market needs and not as per the preferences of the developers. The concept is more business oriented as it is practiced to ensure that the software is developed and launched at the right time.

You can come across varieties of SDLC models which have seen the daylight in the last thirty years. Each of these models has different requirements in terms of specific skill sets, resources and other issues. Similarly, software developers are also motivated to make use of these SDLC models while developing Ajax based applications. After all, Ajax is also a language used to create software. Below are some of the widely used SDLC models and we will decide which one is the most suitable for developing Ajax programs.

There is one model named Rapid Application Development or RAD which is suitable for various genres of software. You can use this model for Ajax programs as it is based on designing models after models and presenting them to end users. It gives much importance to the use of specific tools for building software. One drawback of this model in software development life cycle is that the programs need to be developed quickly for several causes and can result in frustration in building an Ajax based model. You might have the tools, but you have no time.

Waterfall model is the first model to adopt a standard procedure of developing applications. It consists of stages like plan, build and implement. Some programs can be developed in a simple and effective manner using this model. But it is very difficult to create Ajax programs on the basis of this model. Waterfall model is one way and very rigid on certain stages. It doesn’t offer enough freedom to developers to go back at their created software. There is no scope for modifications and revisions. It is also very hard to build a simple Ajax program using this model as systematic review of the built software is impossible.

The prototype model believes in creating a prototype. It makes use of various models. It points to a spiral model that can be used to develop various Ajax programs. The spiral model is a kind of prototype development model that concentrates on each development stage of the software or various sub-stages. There is a prototype created for each stage of the software. When the software comes to an end, all these prototypes are combined to create good software. It is suitable for Ajax based programs as the focus is on developing each component as per its specifications.

Ajax based websites should be as simple as possible. The browser is not well equipped yet for very complicated interfaces. On the other hand, the component assembly makes use of the available codes and applies it for development. It’s perfect for creating simple Ajax based websites.
