Sldc is important because it breaks down the entire life cycle of software devvelopment thus make is easier to evaluate each part of software development and also makes it easier for programmers to work concurrently on each phase.also provide a rough time when software will be available for use.
for gathering data and information.
Its as important as maths is to physics
it is very important to me
why is rot important
he is important because he is awsome
SDLC or System Development Life Cycle is important because it describes the phases that a program developer has to follow to ensure success. The cycle consists of between four and seven steps that a programmer should adhere to in his work.
what are the phases of the sdlc
SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC

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
Planning and Analysis. Many companies only spend 10-15 % on these two phases and in the end they fail because they didn't plan and analyze the product that was needed to invent. Spending more time on these two phases would decrease the failing overtime and reduce expenses by producing a needy product or service.
There are usually two design stages in SDLC. They are:High-level Design &Low-level Design

See the graph in the related link. It clearly separates out the differences between PDLC and SDLC.

The reason why you might not find differences in the sdlc and rad is because RAD is a more sped-up version of the SDLC. RAD is typically used in small to medium size projects, while the SDLC is generally used for large projects. Another difference is that in the SDLC, one can control the scope creep of the project, whereas that is very limited when one implements RAD because you give it up for faster implementation times. In RAD you have alot of feedback from the user to refine the program more to the aspects of the user, whereas you dont get the same user input in the SDLC. This feedback loop is another reason that RAD is sometimes chosen over the SDLC
