Study Notes
Analysis Phase
- The main focus of the Analysis phase in software engineering is on understanding the problem domain and identifying the requirements of the system.
UML Diagrams
- The dynamic behavior of a system in UML is primarily represented using sequence diagrams or state machine diagrams.
- Deployment diagrams are used to represent the physical deployment and configuration of system components.
Process and Use Cases
- The primary purpose of a flow of events in a process or use case is to describe the sequence of activities and interactions between actors and the system.
SDLC Phases
- The activities 'Requirements Elicitation' and 'System Design' take place in the Analysis and Design phases of the Software Development Life Cycle (SDLC), respectively.
Modeling
- A static model focuses on representing the structure and organization of the system's objects and their relationships.
System Design
- The main purpose of subsystem decomposition is to allocate system functionality and responsibilities to subsystems and components.
- Robustness in system design refers to the ability of a system to continue functioning correctly even when errors or exceptions occur.
- In the context of design trade-offs, a common trade-off is between functionality and performance.
- Identifying design goals helps to define the desired properties and characteristics of the system.
Design Process
- One potential difficulty mentioned in the text about the design process is resolving conflicting design goals and trade-offs.
UML Notation
- UML notation commonly used to represent subsystems is packages.
Concurrency Control
- The main purpose of concurrency control in system design is to manage access to shared resources and ensure consistency and integrity.
Design Guidelines
- Availability in the context of system design refers to the ability of a system to be accessed and used when needed.
- When distributing classes on subsystems, the designer should follow the guideline of grouping related classes together to minimize dependencies and improve cohesion.
