RAD

Rapid Application Development

What is RAD and what does that involve?

Fast Application Expansion, or RAD for short, is a method of developing application with the bare minimum amount of planning; this allows the programme or software to be completed considerably faster than traditional software creation. The two most popular LISTA systems happen to be Visual Simple and Delphi.

In what instances would LISTA be used and why?

LISTA would be used when the plan would be under a heavy period constraint, therefore needs to be finished quickly.

What is Prototyping and in what ways is it used in RAD?

Prototyping is an earlier sample or model of a programme inside the purpose to evaluate its uses and to check its simplicity. Prototypes tend to be learned coming from when creating future programmes. In LISTA prototypes are produced prior to the final plan to see if that meets the requirements. Prototypes can then be brought into fresh programmes in order to save time and money in production.

What are the advantages of using prototypes?

The advantages of using representative models is that you can make sure your programme is proper and satisfies requirements just before producing a final product. Its main advantage is that it saves time when generating future programmes, as you know that the prototype functions correctly.

What is iterative expansion?

Iterative expansion is a development technique where the process of: Testing=> Analysing=> Improving

And this method repeats until the programme is about the desired regular. This makes certain that your program has very little faults and errors as it can be.

What is the waterfall technique and exactly what are the stages?

The design model is a process of expansion where the stages " flow” from top to bottom, like a waterfall. The stages happen to be:

Requirements(spec)

Design

Construction

The usage

Testing and debugging

Unit installation

Maintenance.

Evaluate RAD and the Waterfall approach giving pros and cons of each. RAD development is definitely fast and...
