SDLC

[Mark Zuckerberg]

Stands for System Development Lifecycle. SDLC is a structured approach to creating and maintaining a system used in information technology. It can be applied to networks and online services, but is most often used in software development.
When applied to software, the SDLC is also called the application development life-cycle. Some SDLC models have as few as five stages, while others have as many as ten. A typical SDLC framework used for developing a software application might include the following seven stages:
The reason the above stages are referred to as a cycle is because these stages are repeated each time a new major version of the software is released. While the maintenance stage may encompass minor updates, most software companies stay in business by regularly releasing paid updates (version 2, version 3, etc). Before embarking on a new major version, the development team must first create a plan (stage 1) and then continue through the other stages of the SDLC.
