The Classical Software Development Life Cycle (SDLC) is a structured approach to software development that outlines the stages involved in creating software applications. It typically includes phases such as requirements gathering, system design, implementation, testing, deployment, and maintenance. This model is often represented as a linear or sequential process, where each phase must be completed before the next begins, allowing for clear documentation and structured project management. While effective for smaller projects, the rigidity of the Classical SDLC can be a limitation in more dynamic or complex environments.
Requirements analysis phase
for gathering data and information.
time consuming, cost increasing,large number of information nessary to collected
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 .
Projects that exhibit high levels of uncertainty, rapidly changing requirements, or complex stakeholder needs call for an adaptive approach to the Software Development Life Cycle (SDLC). Additionally, when the technology is emerging or when user feedback is critical to development, an iterative and flexible methodology, such as Agile, becomes essential. This allows teams to respond quickly to changes and continuously refine the product based on real-time input and evolving conditions.
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
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
