What Is Software Engineering?
Software engineering is a discipline of computer science dealing with the systematic design, development, implementation, operation, and maintenance of software products.
As Google defines it, software engineering doesn’t only refer to the act of coding or programming new software, but also the process and tools that companies use to build, maintain, test, and update that code over years – in other words, software engineering is computer programming integrated over time.
The software engineering process often begins long before programs or projects have been designed. Typically, the software engineering process requires that companies or clients outline their needs or expectations prior to projects starting. A Software Engineer would then typically oversee a software development team responsible for building, designing and testing a software program that meets those user requirements and continues to meet those user requirements well into the future without a costly amount of maintenance.
Software engineering spans both the front end – the visual, front-facing elements of a system or program – and back end, which applies to the systems used by clients and administrators.
Every Industry Needs Software
A qualified Software Engineer could find a job in virtually any industry, because virtually all companies need software and systems.
Software Engineers could find themselves working in companies in industries including healthcare, gaming, government, transit and logistics, fintech and more. From software testing, updating and debugging to building brand-new apps, systems, games, programs, and infrastructures, Software Engineers have a set of job skills that would be useful at virtually all companies across all industries.
What Are the Fields of Software Engineering?
Software design or architecture spans three levels: interface design, or how systems interact with their environments; architectural design, which looks at systems’ major components; and detailed design, which looks at those major components’ internal elements.
The process of programming or coding, software testing, and debugging – the construction of the software, in other words – constitutes software development.
Software maintenance refers to supporting, modifying, updating, and optimizing software after getting a better understanding of performance on real machines in the real world. Maintenance of software can be one of the most expensive elements of software projects and as a result, cost-effective maintenance is typically a priority.
Requirements engineering spans three different types of requirements – functional, non-functional and domain – and ultimately concerns analyzing, specifying, and validating requirements for software.
Software testing is intended as an objective analysis of the quality of a program, app, or service after applying thorough testing under different formal approaches, including integration testing and unit testing.
