In iterative model we get an end product at the end of each iteration. Iterative model is not so efficient and time consuming.
There are many software development life cycle models , one of them is iterative model. In iterative model at the end of each iteration a useful end product is released.
What is SDLC?A software cycle deals with various parts and phases from planning to testing and deploying. All these activities are carried out in different ways, as per the needs. Each way is known as a Software Development Lifecycle Model (SDLC)What are the different SDLC Models ?1.Rapid application development(RAD) (including methods like SCRUM, Agile & Extreme Programming);2.The linear or waterfall model(which was the original SDLC method);3.Joint application development (JAD);4.The iterative model;5.The v-model;6.The prototyping model;7.The fountain model;8.The spiral model;9.Build and fix;10.synchronize-and-stabilize
spiral model and prototype model
Advantages The project mangers and programmers will able to communicate to each other Components will be easier to define Uncompleted products can be passes on to another person when necessary
SDLC refers to a stage all systems naturally undergo, a methodology refers to an approach invented by humans to manage the events naturally occurring in the SDLC
Software and traditional engineering are somewhat very closely related. Engineering practices like cost and effort estimation are common in both.

There are number of SDLC models in software engineering. Using life cycle model we can divide the work in different phases thus making it easy and convenient .

advantages and drowbacks of following a life cycle approach to information system development?
The Waterfall Model: A classic SDLC model, with a linear and sequential method that has goals for each development phase. The waterfall model simplifies task scheduling, because there are no iterative or overlapping steps. One drawback of the waterfall model is that it does not allow for much revision. the waterfall model is made up of 7 steps: Analysis-> Design-> Implementation-> Testing-> Documentation-> Evaluation-> Maintenance remember it this way: A Dance In The Dark Every Monday!
Build and fix model is the worst model. It does not involve any steps for SDLC and is highly expensive.
