Systems Development Life Cycle (SDLC) is a methodology utilized for the most part as a part of programming advancement, where in every phase of improvement is all around characterized, and done in an organized and methodological way.

The Systems Development Life Cycle (SDLC) started some place in the 1960s, and gives a characterized arrangement of exercises for programming designers to take after.

The critical periods of the Systems Development Life Cycle are:

- Planning

- Requirement Gathering

- Design

- Implementation

- Testing and Maintenance

The motivation behind a Systems Development Life Cycle (SDLC) is to hold fast to customer orders in an organized, successful way and to guarantee better o time conveyance and effectiveness.

SDLC can take after various methodologies, which incorporate nimble and also model based methodologies. There have been numerous models inside SDLC to characterize the stream betterly.

The different models in SDLC are as per the following:

Waterfall Model: Basic, preparatory successive model with four stages

Model

Winding Model: finishes each of the phases of the waterfall display, numerous times while building up the model.

Wellspring Model

Construct and Fix Model

Quick Application Development (RAD)
