Study Notes
Software Engineering
Software engineering is a discipline of software development that applies scientific, economic, social, and practical principles to develop software systems. It involves designing, building, testing, and maintaining complex software systems. Here are some key aspects related to software engineering.
Prototyping Model
The prototyping approach, also known as a rapid application development (RAD) model, creates a simplified version of a software system before developing the complete product. This method helps to identify flaws early and can save time by developing only what is needed instead of more comprehensive systems.
Evolution and Spiral Models
In iterative software development, the evolutionary phase consists of planning and executing changes over several releases based on emerging requirements and new knowledge gained during earlier stages. Spiral models combine elements from both waterfall and incremental approaches, allowing developers to test and improve their software throughout the project's life cycle.
Waterfall Model
Waterfall model, also called linear sequential flow, represents the oldest software development life cycle. In this linear approach, each step must be completed before starting the next one. While it works well for small projects, larger projects may require additional flexibility or iteration steps.
Feasibility Study
A feasibility study determines whether developing a software system is worth pursuing. It includes factors like technical feasibility (can it work?), operational feasibility (will it meet goals?), financial feasibility (is it affordable?), and legal feasibility (does it comply with regulations?).
Functional Requirements
Functional requirements describe how the program should behave when interacting with users, hardware, and other programs. They detail specific outputs given certain inputs and may include performance expectations.
Non-functional Requirements
Non-functional requirements focus on aspects like usability, reliability, security, maintainability, portability, scalability, performance, safety, and others. These qualities may be less visible but still crucial for successful software engineering.
