| Compiler | Noun | A compiler is a special program that translates source code written in a high-level programming language (like Java or C++) into a lower-level language (like machine code) that the computer's processor can directly execute. | The C++ compiler generated an executable file from the source code, highlighting several syntax warnings during the process. |
| Database | Noun | A database is an organized collection of structured information, or data, typically stored electronically in a computer system. It allows for efficient storage, retrieval, and management of data. | All customer order information is stored in a relational database to ensure data integrity and quick access. |
| Framework | Noun | A framework in programming is a pre-written set of code, libraries, and guidelines that provides a standardized structure for developing software applications. It simplifies common development tasks. | Using a web framework like Django or Ruby on Rails can significantly accelerate the development of complex web applications. |
| Function (or Method) | Noun | A function (often called a method in object-oriented programming) is a self-contained block of organized, reusable code designed to perform a single, specific task. Functions help make code modular and easier to understand. | This function is responsible for validating user input to ensure it meets the required format before processing. |
| Git (Official Site) | Noun | Git is a widely-used, distributed version control system designed for tracking changes in source code during software development. It allows multiple developers to collaborate efficiently. | Our team uses Git to manage different versions of the project and to coordinate work on new features. |

Common Phrases Used
Beyond individual coding terms from our Source Code Glossary, developers use many common phrases that are key to understanding source code discussions and project workflows. Learning these expressions will help you navigate team meetings, code reviews, and daily interactions with more confidence. These phrases are part of the everyday developer terminology and are crucial for effective communication within a development team, forming a vital part of your programming vocabulary.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| Pushing code | This phrase refers to the action of sending your locally committed code changes from your personal computer's repository to a shared, remote repository (like one hosted on GitHub or GitLab). It makes your changes available to others. | "I've finished the feature, so I'm pushing code to the development branch now for the team to review." |
| Pull request (PR) | A pull request is a formal proposal to merge a set of code changes from one branch (e.g., a feature branch) into another (e.g., the main development or master branch). It's a core part of collaborative workflows, allowing team members to review the code, discuss potential issues, and approve changes before integration, thereby maintaining code quality. | "Before merging your new authentication module, please open a pull request so the senior developers can review your code." |
| Debugging the application | Debugging is the systematic process of finding and fixing errors, or bugs, in software code that cause it to behave unexpectedly or incorrectly. This involves identifying the root cause of an issue and implementing a solution. | "We spent most of the afternoon debugging the application to figure out why it was crashing on certain user inputs." |
| Refactoring the codebase | Refactoring means restructuring existing computer code—changing its internal structure and organization—without altering its external behavior or functionality. The goal is to improve code readability, maintainability, performance, or reduce complexity. | "The development team agreed that refactoring the codebase for the user management module was necessary to improve its efficiency and make it easier to update in the future." |
| Running a script | This refers to executing a script, which is a small program or a sequence of commands, typically written in a scripting language like Python or Bash. Scripts are often used to automate repetitive tasks, such as deployments, backups, or system administration. | "I'm running a script to automate the daily backup of our production database to prevent data loss." |
| Version control system (VCS) | A Version Control System (like Git, Subversion, or Mercurial) is software that helps developers track, manage, and organize changes to source code and other project files over time. It allows for collaboration, an audit trail of changes, and the ability to revert to previous versions if needed. | "Using a version control system like Git is absolutely essential for collaborative software projects to avoid conflicts and manage project history effectively." |
| Merge conflict | A merge conflict occurs when a version control system (like Git) is unable to automatically reconcile differences in code between two branches that are being merged. This usually happens when two developers have made conflicting changes to the same lines in a file. It requires manual intervention to resolve. | "We encountered a merge conflict when trying to integrate the new feature branch into the main development line; we'll need to resolve it manually." |
