Study Notes

Week 1

Software engineering emerged in the 1960s, addressing the "software crisis".
Key concepts include information hiding to reduce complexity.
Software characteristics include malleability, complexity, usefulness, and evolution.
Software quality attributes are size, human interaction, stability, reliability, security, portability, and cost.
The software project trinity balances the needs of system, users, and development.

Software Engineer Roles and Responsibilities

Users desire quality features and functionality.
Customers seek cost-effective solutions.
Developers aim for shorter development times.

Qualities of a Good Software Engineer

Continuous improvement: Seeking to learn and grow.
Open-mindedness: Considering diverse approaches.
Effective decision-making: Sound judgments in complex situations.
Honesty and integrity: Trustworthy and transparent.
Attention to detail: Meticulous in code and problem-solving.
Strong communication skills: Collaboration with team members.

Week 2

Software processes offer frameworks for organizing tasks in software development.
Agile methods focus on flexibility and customer collaboration. Scrum uses time-boxed iterations (sprints).
Plan-driven/formal methods involve sequential processes with detailed planning and documentation. Waterfall is a linear model with distinct phases.
Distributed/open-source methods emphasize collaboration in a large, distributed community. Bazaar models decentralized development.

Project Management Phases

Pre-development: Exploration, Allocation, Importation
Development: Requirements, Design, Implementation
Post-development: Installation, Operation/Support, Maintenance, Retirement

Software Development Models

Waterfall Model: Sequential phases with limited flexibility.
Spiral Model: Iterative model emphasizing risk management.
Rational Unified Process (RUP): A comprehensive framework with phases and disciplines.
Agile Models: Iterative and incremental, focusing on flexibility and customer collaboration.

Week 3

Requirements engineering focuses on understanding requirements.
Functional and Non-functional requirements are vital for specifying system behavior.
Traditional Techniques, Group Elicitation Techniques, Prototyping, Model-Driven Techniques, Cognitive Techniques, Contextual Inquiry are all methods of gathering requirements.

Week 4

Software architecture focuses on simplifying complex systems via abstraction.
Architectural styles include Layer/Tier, Pipe and Filter, and Client-Server.
Architectural patterns include Model-View-Controller (MVC).
Representations include static, dynamic, and deployment views.
Software architecture is about understanding stakeholder requirements, designing and developing the system architecture, collaborating with development teams and documenting the architecture.

Week 5

Object-oriented design focuses on implementation details and low-level requirements.
Object-oriented design utilizes class diagrams from the UML.

Week 6

Use case diagrams represent the interactions between actors and use cases, which represent specific system functionalities.
Use case scenarios detail the primary sequence of events, including alternatives and exceptions.
Requirements validation ensures completeness, consistency, feasibility, etc. Common flaws include omissions and contradictions.
Design patterns offer reusable solutions for common software design problems.

Week 7

Testing and validation encompass techniques for evaluating systems during and at the end of the development process.
Validation ensures requirements are met, while verification ensures development process steps are completed correctly.
Different types of tests exist, including manual and automated testing.
Testing activities include test design, test automation, test evaluation and test execution which requires technical knowledge across different aspects of the software.

Week 8

Unit testing focuses on the smallest testable units of code.
Unit testing uses assertions to verify expected outcomes.
Test cases help validate aspects of code, including correctness, performance, and learning about the software.

Week 9

Assumptions can be used to conditionalize testing based on inputs or conditions.
Parameterized tests allow input values from different sources, like data files.
Property based-testing identifies properties of a system and creates test cases to cover them all.
Debugging involves systematic steps to identify and resolve errors.
The TRAFFIC method provides a structured approach to debugging.
Debugging includes tracking a problem, reproducing it, automating solutions, finding origins, focusing on the errors, isolating the error and finally correcting the issue.

Week 10

The debugging methodology is crucial to isolate and fix issues.
Techniques include tracing, backtracking, cause elimination, expertise.
Problem tracking tools such as Bugzilla and Jira aid in managing and prioritizing bug reports.
Problem tracking includes problem history, expected behavior.

Week 11

Delta Debugging is a technique for systematically reducing the size of a failing test case.
Fault localization techniques help pinpoint the cause of errors.
Assertions are statements that check the validity of a program's state.
Debugging techniques include tracing, backtracking, cause elimination, and expertise.

Week 12

Key realities of software include constant evolution and increasing complexity.
Different types of software maintenance include corrective maintenance (fixing bugs) and preventive maintenance (preventing future issues).

Week 13

Measuring size and complexity is crucial to evaluating code quality and understand software maintainability.
Techniques like lines of code, method counts, cyclomatic complexity, and object-oriented metrics are used to evaluate structural elements and potential risks.
Refactoring techniques like extract method improve the design and readability of code without altering external behavior.
Common refactoring techniques include Extract Variable, and Test Driven Development.
