Study Notes
Architectural Models
- Architectural models aid in comprehending system structure and component interactions.
- Functional decomposition simplifies a system's functionality into smaller, manageable functions or modules.
Functional Modeling
- Focuses on what a system does rather than how it accomplishes it.
- User perspective is crucial to ensure the system meets specified requirements.
- Use Cases describe user-system interactions to achieve specific goals.
- Activity Diagrams showcase the flow of activities and actions within a system.
- Functional Flowcharts depict the operational flow and functions within the system.
Structural Modeling
- Represents system components, their relationships, and interactions.
- Essential for understanding system architecture and ensuring effective collaboration among parts.
- Components encapsulate functionalities, which can be software modules or hardware units.
- Relationships include associations, dependencies, generalizations, and aggregations.
- Class diagrams illustrate relationships, notable for showing connections such as Customer and Order classes.
Deployment and Maintenance
- Deployment occurs post-testing when a system is installed, configured, and made available for users.
- Maintenance includes system monitoring, updates, and enhancements to address changing requirements.
Behavioral Modeling
- Describes system behavior and responses to stimuli.
- Utilizes state diagrams, sequence diagrams, and collaboration diagrams for dynamic system illustration.
Data Modeling
- Focuses on representing system data requirements and structures.
- Common techniques include Entity-Relationship Diagrams (ERDs) and data flow diagrams.
- Normalization structures data into forms (1NF, 2NF, 3NF) defining organizational rules.
Dimensional Modeling
- Used primarily in data warehousing for organizing data into facts and dimensions.
- Facts refer to quantitative data stored in fact tables, while dimensions are descriptive attributes stored in dimension tables.
System Design
- A crucial phase where analysis phase requirements inform the creation of detailed blueprints for system construction.
- Involves defining architecture, components, modules, interfaces, and data needed to meet specified requirements.
Key Aspects of System Design
- Architectural Design outlines the overall system structure and high-level components.
- Common architectural styles include client-server, layered architecture, and microservices.
- User Interface Design emphasizes creating intuitive, user-friendly interfaces that enhance usability.
- Security Design integrates considerations to protect the system against unauthorized access and data breaches.
