What is Backend Development Glossary?
This section dives into the core terms you'll encounter as you explore backend development. Think of this Backend Development Glossary as your go-to guide for understanding the building blocks of server-side logic and functionality. We'll break down complex technical jargon explained simply, making this web development lexicon accessible to all.
Below is a table outlining key vocabulary for anyone venturing into server-side development.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| API (Application Programming Interface) | Noun | A set of rules and protocols that allows different software applications to communicate with each other. | The mobile app uses an API to fetch user data from the server. |
| Server | Noun | A computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. | The website's files are stored on a remote server. |
| Database | Noun | An organized collection of structured information, or data, typically stored electronically in a computer system. | User credentials are securely stored in the application's database. |
| Framework | Noun | A pre-written set of code and guidelines that developers can use to build applications more quickly and efficiently. | Django is a popular Python framework for backend web development. |
| Middleware | Noun | Software that acts as a bridge between an operating system or database and applications, especially on a network. | Middleware was used to handle request authentication before passing it to the controller. |
| Authentication | Noun | The process of verifying the identity of a user, process, or device, often as a prerequisite to allowing access to resources. | Multi-factor authentication adds an extra layer of security to user accounts. |
| Authorization | Noun | The process of determining whether an authenticated user has permission to access a specific resource or perform an action. | After logging in, authorization checks if the user is allowed to view admin pages. |
| Caching | Noun/Verb | The process of storing copies of files or data in a temporary storage location (cache) so that they can be accessed more quickly. | Caching frequently accessed data can significantly improve application performance. |
| Scalability | Noun | The ability of a system, network, or process to handle a growing amount of work, or its potential to be enlarged to accommodate that growth. | The application was designed for scalability to support millions of users. |
| Deployment | Noun | The process of making a software application available for use. | The team scheduled the new feature deployment for Friday evening. |
| Version Control | Noun | A system that records changes to a file or set of files over time so that you can recall specific versions later. | Git is a widely-used version control system that helps manage code changes. |
| Request/Response Cycle | Noun Phrase | The fundamental communication pattern on the web where a client sends a request to a server, and the server sends back a response. | Understanding the request/response cycle is crucial for web developers. |
| ORM (Object-Relational Mapping) | Noun | A programming technique for converting data between incompatible type systems using object-oriented programming languages. | Using an ORM allows developers to interact with the database using Python objects instead of SQL queries. |
| Scripting Language | Noun | A programming language that is used to automate tasks or write scripts. Often interpreted rather than compiled. | Python is a versatile scripting language often used in backend development. |
| Microservices | Noun | An architectural style that structures an application as a collection of small, autonomous services, modeled around a business domain. | The company decided to refactor their monolithic application into microservices for better maintainability. |
Common Phrases Used
Beyond single terms from our Backend Development Glossary, developers use specific phrases to discuss concepts and processes. This section will help you understand and use common expressions related to backend coding language, making your communication more fluent. These phrases are key for understanding backend concepts in context when working on server-side development projects.
Here are some useful expressions you'll often hear:
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| Push to production | To deploy new code or updates to the live environment where users can access them. | After rigorous testing, we will push to production next week. |
| Handle a request | The process by which a server receives and processes an incoming request from a client (e.g., a web browser). | The server needs to efficiently handle a request for user data. |
| Query the database | To retrieve specific information from a database using a query language (usually SQL). | We need to query the database to get a list of all active users. |
| Set up a server | To configure and prepare a server (hardware or software) to host an application or provide services. | The first step in our project is to set up a server on a cloud platform. |
| Implement authentication logic | To write the code that verifies user identities, typically involving checking usernames and passwords or tokens. | The developer was tasked to implement authentication logic using OAuth 2.0. |
| Refactor the code | To restructure existing computer code—changing the factoring—without changing its external behavior. | We need to refactor the code to improve its readability and performance. |
| Deploy the application | To make the software system operational and available for end-users. This is similar to "push to production". | The team is ready to deploy the application to the staging environment for final checks. |
For more in-depth understanding of some core concepts like APIs, you can refer to resources like the MDN Web Docs on APIs. Understanding what a Database is fundamentally will also be very helpful.
