Software engineering is the branch of computer science that deals with the design, development, testing, and maintenance of software applications. Software engineers apply engineering principles and knowledge of programming languages to build software solutions for end users. Software Project Management is a proper way of planning and leading software projects. It is a part of project management in which software projects are planned, implemented, monitored, and controlled. Software engineering is a rapidly evolving field, and new tools and technologies are constantly being developed to improve the software development process. By following the principles of software engineering and using the appropriate tools and methodologies, software developers can create high-quality, reliable, and maintainable software that meets the needs of its users. Software Engineering is mainly used for large projects based on software systems rather than single programs or applications. The main goal of Software Engineering is to develop software applications for improving quality, budget, and time efficiency. Software Engineering ensures that the software that has to be built should be consistent, correct, also on budget, on time, and within the required requirements. Software Engineering is a systematic, disciplined, quantifiable study and approach to the design, development, operation, and maintenance of a software system.
