History of Software Engineering
As we delve into the origins of software engineering, unique perspectives emerge, revealing the genesis of this significant field.
The Idea Behind the Term
The leap from traditional programming to software engineering traces back to the 1960s. Margaret Hamilton, a renowned computer scientist, is credited with conceptualizing ‘software engineering.’ She coined it while working on the Apollo moon mission to underscore the complexity and significance of her endeavors. Hamilton aimed to elevate the status of programming, transforming it into a discipline synonymous with other engineering fields.
Key Influences to Software Engineering
Several factors have profoundly shaped software engineering. First, the ‘software crisis’ of the 1960s played a pivotal role. This crisis transpired due to a surge in hardware performance that outpaced software capabilities, resulting in widespread system failures. The crisis spurred innovation, leading to the development of software engineering to construct reliable and efficient systems.
Evolution of Software Engineering in the 60s
The 1960s bore witness to transformative events, molding software engineering with consequential breakthroughs and challenges. Among the prominent influences were the software crisis of the time and the resultant birth of structured programming.
Software Crisis
The software crisis, a tumultuous period that rocked the budding tech industry in the 1960s, marked a pivotal moment in the evolution of software engineering. As computer hardware advanced at unanticipated speeds, manufacturers faced a severe software development challenge. Coding errors were rampant, project deadlines overshot, and costs spiralled out of control, forming the crux of what’s called the software crisis.
Mounting complications related to software reliability, efficiency, and maintainability raised alarm, underlining the need for stringent processes and structured methodologies. Above all, this crisis highlighted the stark disparity between the pace of hardware development and the software capable of driving it. As hardware capabilities grew, software struggled to keep up, amplifying the crisis.
The Growth and Refinement Era: 70s and the 80s
This era marks significant advancements in the field of software engineering. Here’s a look into the evolution and refinement of programming and design patterns during the 70s and 80s.
Introduction to Object-Oriented Programming
As software complexity increased, programmers sought new ways to manage it. Here, object-oriented programming (OOP) entered the scene. OOP gravitated around the concept of “objects” — distinct structures in software that encapsulate both data and the functions to manipulate it. Known as methods, these manipulations allowed the creation and interaction of objects, markedly improving software modularity, maintainability, and reuse.
For example, Smalltalk, considered the first complete OOP language, got released in the 70s. It served as an inspiration for many future languages including C++ that emerged in the 80s. Exemplifying OOP, C++ bundled procedural programming with object-oriented features.
The Rise of Software Design Patterns
Continuing into the 80s, the software engineering field encountered growing software complexity. Concurrently, developers began noticing recurring software design solutions across projects. These generalized solutions, termed “design patterns,” aimed at solving complex design problems, promoting code reusability and easing communication between programmers.
