Component-level design in software engineering involves the detailed specification and design of individual software components or modules that make up a larger software system.
Component-level design focuses on breaking down the system architecture into smaller, manageable units called components.
Each component represents a cohesive and reusable unit of software functionality that can be implemented, tested, and maintained independently.
2. Key Points:
Functional Decomposition: The system's functionality is decomposed into smaller units or modules, each responsible for performing a specific task or function.
Interface Specification:
For each component, the inputs, outputs, and interactions with other components are specified through well-defined interfaces.
Data Design:
Data structures and data flows within each component are designed, including how data is stored, accessed, and manipulated.
Algorithm Selection:
Algorithms and methods for implementing the desired functionality within each component are selected and designed.
Error Handling:
Error-handling mechanisms and exception-handling strategies are defined to ensure robustness and reliability.
Concurrency and Synchronization:
If the system involves concurrent execution, mechanisms for managing concurrency, synchronization, and communication between components are designed.
Example:
In an online bookstore web application, component-level design includes breaking down the system into modules like user authentication, product catalog management, shopping cart, and order processing. For the shopping cart module, the design specifies interfaces for adding items, updating quantities, and checkout
