What is Software Programming? A Complete Guide
By Saruque Ahamed MollickIn simpler terms, software programming is the process of breaking down a task into smaller and manageable instructions and translating the instructions into a language the computer can understand and accomplish the task. This process yields a software program.
Computers understand machine language. Picture a series of on/off switches changing state at blazing fast speeds to execute instructions. The language is written in zeros (off switch) and ones (on switch), making it incredibly inefficient and difficult for humans to write.
To ease writing and translating instructions into machine language, you have access to high-level programming languages, compilers, assemblers, and interpreters. So, how do you use these aspects of software programming to develop a software program? Keep reading to discover!
Phases of Software Programming
Conceptualization
To begin with, you must understand the problem the software program should address. Defining the problem involves approaching various stakeholders, including potential users or clients, and listening to their pain points, dreams, and stories.
Meeting with stakeholders helps you define user personas, which are fictional characters representing varied user types who would interact with the potential software program. User personas also outline information, including challenges and pain points, needs, behaviors and skills, and demographics of the possible software users.
After creating user personas, you ideate or brainstorm how the software can solve the problem. To ease the brainstorming process, develop scenarios and define requirements.
In essence, scenarios are narratives highlighting how users interact with the software to achieve various objectives. On the other hand, requirements identify the potential software’s essential features, functionalities, and constraints based on the stakeholders’ needs and goals.
Using the scenarios and requirements, you can then develop initial software design concepts and undertake a feasibility check.
Initial design concepts can be quick sketches to better understand the expected functionality of the software. From these sketches, you’d be able to determine whether the available resources and budget, including the potential risks and constraints, favor the success of the project. This process of evaluating the possibility of the software being a reality with what is available is referred to as feasibility analysis.
Design
If you find the software program project feasible, undertake user experience and interface design (UI/UX).
UI/UX involves studying the users’ needs and defining how best they can interact with the software’s functionality. From this comes elaborate sketches and digital designs showcasing screen layouts, visual elements, navigation flow, and other interactive features.
Other design elements include database, performance, security, and scalability design. While developing these designs, you progressively determine the technology you’ll use to develop the software. Technology here includes the programming language, libraries, and frameworks you can use to make the software development process successful.
Due to the complexity of software programming, readily available libraries like the Python requests library can save you time. Libraries are a set of pre-written or reusable software components, so you won’t spend time writing code from scratch. The same goes for frameworks. Moreover, other reusable software pieces like packages, modules, and dependencies are aimed at optimizing the software-building process.
Coding and Execution
Based on the design requirements and specifications defined in the design phase, you now convert the designs into computer code using a select programming language.
Writing code involves implementing various software functionalities and features. Frontend code helps the user interact with the software, and backend code manipulates data and processes user requests.
For front and backend code, you must define algorithms, create data structures, integrate external components like libraries, modules, and packages, and infuse business logic into the code.
After integrating each component of the software, you feed the code into a compiler, assembler, or interpreter to execute it. Your choice of what to use to execute the code is based on the selected programming language.
Debugging and Testing
Debugging and testing software entails identifying and fixing errors and issues with the software. You aim to ensure the software meets the defined requirements and performance standards.
You should allow the stakeholders to interact with the software, assess its usability, and provide feedback about their overall satisfaction with its functionality. Analyzing the feedback gives you insight into the discrepancies between the users’ needs and the software’s ability to satisfy them.
Moreover, you should carry out a security test. This involves assessing the software’s resilience to security vulnerabilities and threats. You can have security testers examine the software to identify security risks, including injection attacks, data breaches, and unauthorized access.
Deployment
After the debugging and testing phase, you can then develop a rollout strategy defining the deployment environments, configurations, data migration process, and more. The goal is to have a straightforward process of making the software available to a broader user base.
A rollout strategy helps manage and control the release of various phases and versions of the software and more. Also, if the software requires you to migrate data to multiple servers, the rollout strategy optimizes the move of data from one point to the other without corruption or loss.
Maintenance and Updates
Even after deploying the software to users, you must keep fixing bugs, optimizing performance, and adapting to technological changes. Not adapting to technological changes may lead to incompatibility with technology, including browsers, operating systems, and dependencies, leading to software crashes.
Moreover, the first batch of users will report the issues, bugs, and errors they spot, requiring you to investigate the reports and implement corrective actions. Moreover, in case security issues arise, you should be ready to patch them promptly.
It is up to you to improve the software continuously. Learn from user feedback, old software releases, and industry best practices to stay afloat. Missing out on this leads to a decline in the relevancy and need of the software.
Closing Words
Software programming is the backbone of all the software applications or programs you use. It is not a one-time process, though. Software programming involves defining instructions for a computer to follow and finalize a task. So, you must keep iterating the software solution as the approach to solving the problem changes.
Remember, when done well, software programming can result in a software solution capable of automating monotonous tasks, saving you a lot of time and energy. So, keep digging into how you can optimize the functionality of the software you develop.
