Introduction to Software Engineering
- Software is a collection of executable code, associated libraries, and documents.
- Software engineering is the application of scientific principles and methods to building software products.
Need of Software Engineering
- Large software: It is easier to construct smaller items. For large software, a systematic method is required.
- Scalability: Easy to create new software than improving existing software if methods are unsystematic.
- Cost: Hardware costs reduced. But good software development methods can lower software costs.
- Dynamic nature: Software evolves. So, software engineering is required since the environment changes.
- Quality management: Better development processes lead to better quality software.
Characteristics of Good Software
- Operational: Measured by budget, usability, efficiency, correctness, functionality, dependability, security, and safety.
- Transitional: Measured by portability, interoperability, reusability, and adaptability.
- Maintenance: Measured by modularity, maintainability, flexibility, and scalability.
Software Development Life Cycle (SDLC)
- A life cycle model describes and diagrams software activities.
- It shows the order of tasks in developing, implementing, and retiring a product.
- Activities can be done in different orders in different models.
Need for a Software Life Cycle Model
- Teams need a clear understanding of tasks and timelines.
- Without SDLC, there are risks like chaos, failure, and confusion among team members.
Types of Life Cycle Models
- Classical Waterfall
- Iterative Waterfall
- Prototyping
- Evolutionary
- Spiral
Classical Waterfall Model
- Intuitive but not practical for most projects.
- Phases: Feasibility study, requirements analysis, design, coding, testing, maintenance.
Feasibility Study
- Determining if a project is financially and technically viable.
- Understanding client requirements, cost, time and availability of resources.
Requirements Analysis and Specification
- Understanding customer needs and documenting them.
- Requirements gathering: Collecting information from clients through discussions and investigations.
- Requirements specification: Detailed description of the software's functional and non-functional requirements.
Design
- Transforming requirements into an implementable structure.
- Traditional design: Structured analysis and design.
- Object-oriented design: Identifying and defining objects.
Coding and Unit Testing
- Implementing the design as source code.
- Testing individual modules (unit testing).
Integration and System Testing
- Integrating individual modules.
- Testing the whole system (system testing) using various approaches (α, β, acceptance testing)
Maintenance
- Corrective: Fixing errors detected after deployment.
- Perfective: Improving existing features to meet changing needs.
- Adaptive: Modifying software to run on different platforms.
Shortcomings of Classical Waterfall Model
- Assumes no errors, which is not realistic.
- Difficult to correct issues once detected.
