Definition
Software Engineering is a systematic, disciplined,
and quantifiable approach to the development,
operation, and maintenance of software.
Software Development Life Cycle (SDLC)
SDLC is a structured process used by organizations to
build high-quality software. It consists of the following
phases:
Planning: Estimating costs, resources, and time.
Design: Creating the software architecture
(High-level and Low-level design).
Implementation (Coding): Translating design
into source code.
Testing: Verifying the software against
requirements to find bugs.
Deployment & Maintenance: Releasing the
product and fixing future issues.
