Study Notes
Course Information
- Course Title: Software Engineering
- Course Number: CSE 2410
- Instructor: Khaled Slhoub, PhD
- Required Reading: Chapter 1
Software Defined
- Software is pervasive in modern life: buying groceries, driving, clothes washing, etc.
- Synonyms: programs, applications
- Applications: Software that interacts directly with users
- Software is often used in databases: record names and addresses
Software Engineering Defined
- Software engineering (SE): A branch of engineering concerned with software product development
- SE principles, best practices, and methods evolve over time to deal with changes in software technologies
- Reliable, efficient, effective software is the key outcome of SE
Software Engineering Details
- The study of developing software systems, from requirements to maintenance.
- Collaborative team work is fundamental, including communication and management.
- Understanding users and their needs is crucial, to design and measure results, plus analyze processes
Software Properties
- Software is a unique type of product and has distinct properties that differentiate it from other products.
- Key properties include: invisibility, complexity, changeability, conformity, discontinuity, as well as issues around requirements volatility
- Large systems/products are difficult for people to understand easily and may have discontinuous behavior.
Historical Context
- Software emerged as a distinct technology in the 1950s, independent from hardware
- Original programmers were recruited from hardware engineering and mathematics, using ad-hoc techniques.
- The concept of Software Engineering first emerged in 1968 as a result of problems with early software systems.
Paradigm Shifts
- The 1970s marked a fundamental shift in software engineering, largely as a result of the increasing size and complexity of software systems.
- These systems required new, systematic approaches.
- The Waterfall Model: The first published software development process model, requiring a rigid order of steps.
- The Cost of Changes: Making adjustments later in a project is much more costly and complex than making changes earlier.
The Software Crisis
- Problems with early software:
- High costs exceeded predictions
- Unreliability of the software
- Difficulty in maintaining the code.
- Issues in the software were so critical and common that the idea of a discipline called Software Engineering was born.
Iterative Paradigm
- The iterative paradigm emphasizes software evolution, in contrast to the rigid framework of the waterfall model, particularly in large long-term projects..
- Current software practices favor iterative and incremental approaches.
Project Success and Failures
- Factors contributing to project failure: incomplete requirements, and lacking user involvement.
- Effective project management, user input and clear communication are essential drivers for project success.
- The Standish Group's research provides insight into project success and failure patterns.
Current Industry Trends
- Current software engineering practice places emphasis on safe and secure intelligent software, for example AI.
- There is still room for improvement in software development.
Requirements Analysis
- Methodologies utilized in software requirements analysis.
- The IEEE standard for requirements analysis steps that specify the functions and performance of a software system, along with how the software should interact with its environment, users and other systems.
Software Design and Architecture
- Different approaches for software design and architecture
- A variety of methods are available to help manage the process.
Software Coding and Implementation
- Description of this step is shown via the diagram
- The coding involves implementation techniques, using programming languages, and associated tools.
Software Testing
- Various testing mechanisms and steps to ensure quality.
- Different types of software testing strategies are shown by diagram
Conclusion
- Software engineering paradigm shifts have led to current best practices.
