Software engineering is an engineering method for systematics application software development.
A person who designs, develops, maintains, tests, and evaluates computer software using software engineering concepts is a software engineer. The term programmer is occasionally used interchangeably, but it does not always imply an engineering degree or expertise.
The software development process, which includes the definition, implementation, evaluation, measurement, management, modification, and improvement of the software life cycle process itself, is informed by engineering methodologies. It makes extensive use of software configuration management, which is concerned with methodically regulating configuration changes and ensuring the integrity and traceability of configuration and code across the system life cycle. Software versioning is used in modern workflows.
The tasks of a software engineer include:
Software requirements - elicitation, analysis, definition, and validation of software requirements are all part of requirements engineering.
Software design - Programming, unit testing, integration testing, and debugging are all part of software design.
Software construction
Software testing
Software maintenance
