'V' shape model describes about the process about the construting the application at a time all the Analysing, designing, coding and testing will be done at a time. i.e once coding finishes it'll go to tester to test for bugs if we got OK form tester we can immediately start coding after coding again send to tester he'll check for BUGS and will send back to programmer then he,programmer can finish up by implementing the project.
it is the model what is using by most of the companies.
v model is model in which testing is done prallelly with development.left side of v model ,reflect development input for the corresponding testing activities.
V Model is the process model to provide quality product by combining SDLC and STLC. In this model Both SDLC & STLC works parallely. Left Hand side of the V model contains SDLC in downhill direction whereas right hand side of the V model contains STLC in Uphill direction
V model is the classic software development model. It encapsulates the steps in Verification and Validation phases for each step in the SDLC. For each phase, the subsequent phase becomes the verification (QA) phase and the corresponding testing phase in the other arm of the V becomes the validating (Testing) phase
Traditional Water fall model will not allow to do the testing and the coding process in parallel. V - model in the SDLC will allow the process to have testing and coding as a parallel activity which enables the changes to occur more dynamic.
V- model is a process where the development and testing phases can do parallely. For every development phase there is a testing phase. Development phases are called as verification whereas testing phases are called as validation. Here verification means the software implements correctly or not. Validation means the software that has been built is traceable to the customer requirements or not.
