Here, we’ll cover some background information that will help you better understand the field of software engineering (and decide if you want to become a software engineer!).
The History of Software Engineering
As mentioned earlier, software engineering is used in the development and launching of rockets, and this is actually where the term was coined. Before the 1960s, the title of “engineer” was reserved only for complex physical machines. But as computer scientist Margaret Hamilton worked on the guidance and navigation systems for the Apollo missions, she decided the work done by her team deserved the same title. Within the decade, the first NATO software engineering reports were also released.
It took a while for the term to take hold, but by the 1970s, new ideas and programming languages such as Pascal and C started to appear along with the first personal computers (PCs). In 1979, Seattle University began offering its first degree in computer engineering.
In the 1980s, the C++ programming language was introduced, and object-oriented programming became popular. In 1989, the internet made its first appearance. From the 1990s onwards, video game consoles, home computers, phones, smartphones, tablets, and all sorts of technological innovations using complex software have become prevalent in our society.
The Goals of Software Engineering
A primary goal of software engineering is to enable the average user to interact with a computer—software allows us to send commands with the click of a button rather than typing out lines of code into a terminal. Software even helps users create complex projects with limited technical knowledge, such as website building software or game engines.
Is Software Engineering the Same As ….?
There are many niches and individual fields within the software industry, so we’ll cover a few here that are closely related to software engineering.
vs. Machine Learning
Machine learning is a discipline of artificial intelligence (AI) that allows a software application to learn from data fed to it and improve performance on tasks. It is related to software engineering in the sense that coding is required to design and manage these kinds of systems, but machine learning and software engineering are two very different disciplines.
vs. Computer Science
Computer science is an area of study related to how computers work and the various ways we can interact with them. Many professional software engineers have degrees in courses titled Computer Science, where they study topics like programming languages, operating systems, and algorithms. Unlike software engineering, the study of computer science isn’t directly connected to the development of software.
vs. Data Science
Data science is a specific area within the software industry that deals with the analysis and manipulation of large data sets. While programming languages are used to create programs and algorithms that can store and sort the data, the field is not connected to the creation of user software in the way that software engineering is.
