The Software Development Life Cycle (SDLC) is a structured approach used for planning, developing, testing, and deploying software applications.

Elaboration:

• Consists of six main phases: Planning, Analysis, Design, Implementation, Testing, and Maintenance.
• Helps manage resources, time, and risks in software projects.
• Common SDLC models include Waterfall, Agile, and Spiral models.

Example:

A banking application follows SDLC to ensure security and compliance before deployment.
