Frequently Used Terms in Software Engineering

1. Agile Development: Agile development is an iterative software development methodology that focuses on flexibility and adaptive planning. It emphasizes collaboration, continuous improvement, and delivering smaller increments of working software.
2. API: API stands for Application Programming Interface and refers to a set of rules and protocols that allow different software systems to communicate with each other. It defines the methods and data formats used for interaction between different software components.
3. CI/CD: CI/CD is an acronym for Continuous Integration and Continuous Delivery or Continuous Deployment. It is a set of practices and tools that automate the process of building, testing, and deploying software changes frequently and reliably.
4. Debugging: Debugging is the process of finding and fixing errors or bugs in software code. It involves identifying the root cause of a problem by analyzing the code and its execution behavior, often using tools and techniques like setting breakpoints, stepping through the code, and inspecting variables.
5. Dependency Injection: Dependency Injection is a design pattern used in object-oriented programming to achieve loosely coupled and modular code. It involves injecting the dependencies of a class from external sources, rather than having the class create them internally, promoting reusability and testability.
6. Git: Git is a popular distributed version control system used in software development to track changes in source code. It provides features like branching, merging, and version history, enabling collaboration and efficient management of code repositories.
7. IDE: IDE stands for Integrated Development Environment, which is a software application that provides a comprehensive set of tools and features for software development. An IDE typically includes a code editor, build automation, debugging tools, and integration with version control systems.
8. Legacy Code: Legacy code refers to existing software code that was developed in the past and is still in use. It is often outdated, hard to maintain, and lacks proper documentation or test coverage. Refactoring or rewriting legacy code is common to improve its quality and maintainability.
9. MVC: MVC stands for Model-View-Controller, which is a software architectural pattern commonly used in web application development. It separates the application into three components: the model (data and business logic), the view (presentation and user interface), and the controller (handles user input and coordinates the model and view).
10. Scalability: Scalability refers to the ability of a software system to handle increasing workloads and accommodate growing user demand efficiently. It involves designing and building systems that can handle higher traffic, larger datasets, and increased complexity without significant performance degradation.
11. Secure Coding: Secure coding refers to the practice of writing software code with a focus on preventing, detecting, and mitigating security vulnerabilities. It involves following secure coding guidelines, using encryption, input validation, and secure coding patterns to minimize the risk of attacks like injection, cross-site scripting, or data breaches.
12. Unit Testing: Unit testing is a software testing technique that involves testing individual components or units of code to ensure they behave as expected. It typically involves writing automated tests that verify the correctness of specific functions, methods, or classes in isolation from the rest of the system.
13. Version Control: Version control is a system that helps manage changes to a set of files or source code over time. It enables multiple developers to work on the same codebase concurrently, keeps track of changes, allows reverting to previous versions, and facilitates collaboration and code review.
14. Waterfall Methodology: The waterfall methodology is a traditional software development approach where each development phase, such as requirements gathering, design, implementation, testing, and deployment, occurs sequentially. It follows a linear and structured flow, with one phase starting only after the completion of the previous one.
15. XML: XML stands for Extensible Markup Language and is a commonly used format for structured data representation. It separates data from presentation and is widely used for data exchange and storage. XML documents consist of nested elements with tags and attributes to define their structure.
