Custom software development is like building a tailor-made suit. Instead of buying something off the rack, you design and create a garment that fits perfectly. This involves understanding the client’s specific needs, creating a design, and then crafting the software to match those requirements precisely.
Stages of custom software development
1.Requirement gathering
This is the foundational stage where the software’s purpose is defined. It involves identifying client needs and goals, conducting feasibility studies, and creating detailed functional specifications.
2. Design
The design phase outlines the software’s architecture, user interface, and database structure. Key activities include creating wireframes and prototypes, defining data models and relationships, and designing the software’s overall structure.
3. Development
This stage involves writing the actual code for the software. Activities include building the user interface, developing the backend
The backend is like the kitchen. You don't see it, but it's where all the magic happens. The chefs prepare your food (process data), the kitchen staff manages ingredients (stores data), and the dishwasher cleans up (data management). The waiter (frontend) brings you the food (information), but the real work happens behind the scenes in the kitchen (backend).
Backend definition
Backend refers to the server-side of a software application or website, responsible for business logic, data management, and application functionality. It encompasses the underlying infrastructure and processes that support the user interface.
Backend components
The server is the backbone of a backend system. It's a powerful computer that handles requests from clients (like web browsers or mobile apps), processes them, and sends back responses. Imagine it as a receptionist directing visitors and providing information.
A database is where information is stored and organized. It's like a digital filing cabinet for the application. There are different types of databases (relational, NoSQL) to suit various data storage needs.
Application logic is the brain of the application. It defines how the application should respond to different inputs and requests. It's the set of rules and calculations that determine the output. For example, calculating the total cost of a shopping cart or verifying user login credentials.
API (Application Programming Interface) is a set of rules for building and interacting with software applications. It's like a contract defining how different parts of the system communicate. For example, a mobile app might use an API to fetch data from a backend server.
These components work together to create a functional backend system. The server handles requests, the database stores data, the application logic processes information, and the API facilitates communication between different parts of the system.
Backend processes examples
Backend processes encompass a wide range of activities that ensure the smooth functioning of a web application. Here are some examples:
User authentication and authorization
Verifying user credentials (username, password) against a database.
Generating and managing session tokens.
Enforcing access controls based on user roles and permissions.
Data management
