Study Notes

Modeling

  • Models abstract a system at various levels of detail and precision
  • Object-oriented methods address software modifiability, adaptation, and evolution

Unified Modeling Language (UML)

  • A graphical language for describing models

Software Architectural Design

  • Separates overall system structure and interconnections

Programming-in-the-Small

  • Detailed design of individual components

Programming-in-the-Large

  • Emphasizes component interconnections

Levels of Software Architecture

  • High level: Decomposes the system into subsystems
  • Low level: Decomposes subsystems into components

Multiple Views of Software Architecture

  • Use case view: Input for developing new features
  • Static view: Relationships and associations
  • Dynamic state machine view: Internal control and sequencing
  • Structural component view: Interconnected parts
  • Dynamic concurrent view: Distributed modes communicating by messages
  • Deployment view: Component assignment to hardware tools

Software

  • A set of machine-readable instructions for specific functions

Software Types

  • System software: e.g., Operating System
  • Programming Tools & Language Translators
  • Application Software:
    • Custom software
    • Generic software
    • Embedded software

Software Engineering

  • Analytical approach to design, development, use, and maintenance

Ad hoc programming style

  • Build & fix, code and fix

Software Crisis

  • Projects failing to be reliable, on time, or within budget

Architecture

  • Design of application software, protocols, and expansion means

System

  • Collection of components, items, or equipment for a specific function

Architectural Design

  • Used for defining complex systems for processors

Common Activities in Software Projects

  • Requirement and Specification
    • Domain Analysis: Understanding the background
    • Defining the problem: Determining the precise problem to solve
    • Requirement Gathering: Obtaining all ideas
    • Requirement Analysis: Organizing the gathered information
    • Requirement Specification: Defining what and how the software should function
  • Design
  • Modeling
    • Use case modeling: Representing the sequence of actions performed
    • Structural modeling: Representing things as classes and objects
    • Dynamic & Behavioral Modeling: Modeling the activities that can be performed
  • Programming: Translating design into programming language
  • Quality Assurance: Reviews, inspections, and testing
  • Deployment: Distributing and installing the software

Requirement Modeling

  • Actors and use cases: Describing what the user expects from the system

Quality Attributes

  • Correct
  • Complete
  • Unambiguous
  • Consistent
  • Verifiable
  • Understandable by non-computer specialists
  • Modifiable
  • Traceable

Use Case Modeling

  • Defines the functional requirements of the system in terms of actors and use cases

Use Case

  • Defines the sequence of interactions between actors and the system
  • Represented by ovals

Main Sequence

  • Most common sequence of interactions between the actor and the system

Alternative Sequence

  • Frequent interactions between the actor and the system

Scenario

  • Each sequence through the use case

Association

  • Communication between an actor and a use case
  • Represented by lines

Actors

  • An external user
  • A role played in the application domain
  • Represented by stick figures
  • Primary actors: Initiate a use case
  • Secondary actors: Participate in the sequence

System Boundary

  • The scope or limits of the system

Software Requirement Specification

  • A traceable document

Relationships

  • Dependencies between use cases
  • Include: Occurs when there is a common sequence
  • Extend: Models alternative paths a use case might take

Activity Diagram

  • Shows the flow of control and sequencing among activities
  • Represents the sequence of activities, decisions, nodes, loops
