Quick Reference

RESTful API

An architectural style for designing networked applications that uses standard HTTP methods (GET, POST, PUT, DELETE) to perform CRUD operations on resources identified by URLs. REST APIs are stateless, meaning each request contains all information needed to process it.

Model-View-Controller (MVC)

A software design pattern that separates an application into three interconnected components: the Model (data and business logic), the View (user interface and presentation), and the Controller (handles input and updates the model and view).

Single Page Application (SPA)

A web application that loads a single HTML page and dynamically updates content as the user interacts with the app, rather than requesting entirely new pages from the server. This approach provides a smoother, app-like user experience.

Object-Relational Mapping (ORM)

A programming technique that maps database tables to objects in an application's programming language, allowing developers to interact with the database using the language's native syntax rather than writing raw SQL queries.

Middleware

Software that sits between the client request and the server response in a web application, performing tasks such as logging, authentication, error handling, or data transformation before the request reaches its final handler.

Responsive Design

An approach to web design that ensures a website's layout and content adapt fluidly to different screen sizes and devices, using techniques like flexible grids, media queries, and relative units.

Version Control (Git)

A system that records changes to files over time so that specific versions can be recalled later. Git is a distributed version control system that enables multiple developers to collaborate on the same codebase through branching, merging, and pull requests.

Continuous Integration / Continuous Deployment (CI/CD)

A set of practices where code changes are automatically built, tested, and deployed to production. CI ensures that new code integrates cleanly with the existing codebase, while CD automates the release process.

Database Normalization

The process of organizing a relational database to reduce data redundancy and improve data integrity by dividing large tables into smaller, related tables and defining relationships between them using foreign keys.

Authentication vs. Authorization

Authentication verifies a user's identity (who they are), while authorization determines what resources and actions an authenticated user is permitted to access (what they can do). Both are essential for application security.

Key Terms at a Glance

API (Application Programming Interface):A set of rules and protocols that allows different software applications to communicate with each other by defining endpoints and data formats for requests and responses.

Authentication:The process of verifying the identity of a user or system, typically through credentials such as username/password, tokens, or biometrics.

Authorization:The process of determining what actions or resources an authenticated user is permitted to access, often implemented through roles and permissions.

Back End:The server-side portion of a web application responsible for business logic, database interactions, authentication, and API endpoints that the front end consumes.

Cache:A temporary storage layer that holds frequently accessed data to reduce database queries and API calls, improving application performance and response times.

CI/CD:Continuous Integration and Continuous Deployment. Automated practices for building, testing, and deploying code changes to production environments.

CORS (Cross-Origin Resource Sharing):A browser security mechanism that controls which external domains can access resources on a web server, configured through HTTP response headers.

CRUD:Create, Read, Update, Delete. The four basic operations performed on persistent data, corresponding to HTTP methods POST, GET, PUT/PATCH, and DELETE.

CSS (Cascading Style Sheets):A stylesheet language used to describe the visual presentation of HTML documents, controlling layout, colors, typography, animations, and responsive behavior.

Docker:A platform that uses containerization to package applications with all their dependencies into portable, isolated units called containers that run consistently across environments.

DOM (Document Object Model):A tree-structured programming interface representing an HTML or XML document, allowing JavaScript to read, modify, add, and delete elements and content dynamically.

Endpoint:A specific URL in a web API where a client can send requests to interact with server resources, typically associated with a specific HTTP method and resource.

Front End:The client-side portion of a web application that users interact with directly, built with HTML, CSS, and JavaScript and rendered in the web browser.

Git:A distributed version control system for tracking changes in source code, supporting branching, merging, and collaborative development through platforms like GitHub and GitLab.

GraphQL:A query language and runtime for APIs that allows clients to request exactly the data they need from a single endpoint, avoiding over-fetching and under-fetching common in REST.
