Study Notes
Software Overview
- Software is capable of performing many tasks, unlike hardware which can only perform mechanical tasks it is designed for.
- Examples of software include Google Chrome, Skype, CCleaner, VLC, Adobe Reader, Firefox, etc.
Software Evolution
- Software evolution is the process of developing a software product using software engineering principles and methods.
- It starts from the requirement gathering process.
- 8 Laws for Software Evolution:
- Continuing Change: a software system must continue to adapt to real-world changes.
- Increasing Complexity: a software system evolves.
- Conservation of Familiarity: familiarity with the software or the knowledge of how it was developed must be retained at any cost.
- Continuing Growth: in order for a system intended to resolve some business problems, the changes grow according to the lifestyle changes of the business.
- Feedback Systems: constitute multi-loop, multi-level feedback systems.
- Self-regulation: system evolution processes are self-regulating.
- Organization Stability: average effective global activity rate in an evolving system is invariant over the lifetime of the product.
- Reducing Quality: declines in quality unless rigorously maintained and adapted to a changing operating environment.
Software Categories
- System Software: helps run the computer hardware and computer system.
- Application Software: allows users to accomplish one or more tasks. Examples include Microsoft Office, LibreOffice, Photoshop, Window Player, Skype, etc.
- Programming Software: a set of tools to aid developers in writing programs.
Modelling Requirements Analysis
- Requirements Modelling Approaches include:
- Structured analysis: considers data and the processes that transform the data as separate entities.
- Object-oriented analysis: focuses on the definition of classes and the manner in which they collaborate to effect customer requirements.
- Types of Models:
- Scenario-based Models: requirements from the point of view of various system actors.
- Data Models: depict the information domain for the problem.
- Class-oriented models: represent object-oriented classes (attributes and operation) and the manner in which classes collaborate to achieve system requirements.
- Flow-oriented Models: represent the functional elements of the system.
- Behavioral Models: depict how the software behaves as a consequence of external events.
