Study Notes
Introduction to Software Engineering
- Software engineering is a discipline that focuses on all aspects of software production, spanning from the initial stages of system specification to the maintenance phase after its release.
- This discipline aims to create well-designed, developed, and maintained software systems.
- The 1968 NATO Software Engineering Conference introduced the term "software crisis," highlighting the challenges in software development.
Software Engineering vs Computer Science
- Computer science deals with theoretical foundations, while software engineering focuses on practical aspects of software design, development, and delivery.
- Edsger Dijkstra, a prominent computer scientist, is credited with the statement, “Computer science is no more about computers than astronomy is about telescopes.”
Types of Software
- Generic Products: Standalone software marketed to any customer. Examples include general-purpose software like graphic programs or project management tools. Developers own the specification.
- Customized/Bespoke Products: Software commissioned by a specific customer to meet their unique needs. Customers define the specification for the software. Examples include systems like embedded control systems or specialized software for particular industries.
Frequently Asked Questions about Software Engineering
- What is software? A computer program and associated documentation; software can be designed for a particular customer or marketed broadly.
- What are the attributes of good software? Good software should deliver the required functionality and performance effectively to a user. It also requires ease of maintenance and should be reliable, dependable, and usable.
- What is software engineering? An engineering discipline dealing with all aspects of software production, encompassing the entire development lifecycle.
- What are the fundamental software engineering activities? These activities include software specification, development, validation, and evolution.
- What is the difference between software engineering and computer science? Computer science focuses on the theory behind software, whereas software engineering focuses on practical application.
- What is the difference between software engineering and system engineering? Software engineering is focused on software itself and its creation, development, and delivery. System engineering considers all parts of a system. This includes computer-hardware details and processes.
Software Process
- Software process involves activities and results leading to a software product creation. The core activities are specification, development, validation, and evolution.
Software Process Models
- Different models exist to represent a software process, including the Waterfall approach, iterative development, and Component-Based Software Engineering (CBSE).
The Cost of Software Engineering
- Factors determining software cost include the chosen development process and the specific software being developed.
- Development costs usually account for a significant portion of overall costs; testing costs represent another sizeable portion.
- In custom software, evolution costs frequently surpass development costs.
Cost Distribution (Custom vs Generic)
- The cost distribution among various development stages (specification, design, development, testing, and maintenance) can vary significantly depending on the type of software: bespoke (custom) or generic.
- Generic software often has most of the costs concentrated in system testing. Bespoke development often has higher costs in the initial stages of design and the evolution phases later in the lifecycle.
What is CASE?
- CASE stands for Computer-Aided Software Engineering.
- CASE tools support software engineering activities such as requirements analysis, system modeling, debugging, and testing.
Attributes of Good Software
- Functional Attributes: Describe what a software system does, including performance considerations.
- Non-functional Attributes (Quality Attributes): Describe how a software system performs, such as usability, maintainability, dependability, and efficiency.
Challenges Facing Software Engineering
- Heterogeneity: Software must accommodate diverse computing platforms and support environments.
- Delivery: Businesses need software solutions delivered more quickly.
- Trust: Software must be trustworthy, operating reliably and securely in various aspects of people's lives, including work, study, and personal use.
General Policy (from the slides)
- No make-up quizzes, grades, or presentations.
- Make-up midterms are available from the beginning to the end of the tenth week of the course. No medical excuses are required.
- No excuses for absence from lectures are accepted unless there's an official warning or disciplinary action.
- No excused absences for late submissions or missing classes.
Grading (from the slides)
- Final exam: 40%
- Midterm exam: 20%
- Quizzes: 10%
- Individual assignments: 10%
- Group project: 20%
- Passing grade: 60% or higher
