Software Engineering Overview
- Software engineering is the disciplined application of engineering principles to design, develop, maintain, test, and evaluate software systems.
- The goal is producing high-quality, reliable, efficient, and scalable software that meets functional and non-functional requirements cost-effectively.
- The success of software development relies on two interrelated methodologies: software development lifecycle and project management.
- Software is defined as code, data structures/files, and documents describing the construction, operation, use, and maintenance of software systems.
- Core focus is object-oriented software design and software quality.
Software Development Lifecycle Stages
- The software lifecycle includes phases from initial idea to retirement.
Conceptualization
- A stakeholder identifies a need, proposes a system, and creates a business case.
- A business requirements document outlines the goals from the client's perspective.
Requirements Analysis
- Product requirements are determined through negotiation among stakeholders.
- Key questions are addressed, such as identifying the owner, inputs, outputs, data formats, computations, and expected response times.
System Requirement Specification
- Developers create a document that outlines the complete system requirements based on stakeholder needs.
- It includes software, hardware, system interfaces, performance, security, and compliance requirements.
Software Requirement Specification
- This expands on all software requirements, detailing functionality, features, and behavior.
- It formalizes functional and non-functional requirements, user interface design, interaction flow, and system interfaces.
- The final document may include input/output formats, data handling, performance metrics, and design considerations.
Design Phase
- Software design involves determining how to construct the software system to meet expectations, focusing on architecture, components, interfaces, database, and interactions.
- The objective is a robust, maintainable, and scalable system through translating requirements into a structured solution.
Architectural (High-Level) Design
- This stage defines the overall system structure including components, interactions, and external interfaces to fulfill functional and non-functional requirements.
- The system architecture document includes high-level components, patterns, external interfaces, technologies, and frameworks.
Component (Low-Level) Design
- The system is described in terms of modular components corresponding to specific business processes or units of functionality.
- Considers component structure, scope, functionality, and interactions, along with reusability.
- The low-level design document details algorithms, data structures, and interactions, emphasizing high cohesion and low coupling.
Interface Design
- The system will communicate with other systems via the Application Programming Interface (API)
- It is also critical to be user friendly with the User Interface (UI) Design
- API documentation describes the APIs and how to use them.
- UI documentation ensures consistency in design
Database Design
- Data structures decided, and how they are stored, retrieved and managed
- Data integrity is preserved
- The design document covers data model, database entities, relationships, normalization, constraints, and data security.
Coding (Implementation)
- Code and related implementation documents are developed, with source code comments and version control logs for tracking.
Testing
- The code is tested against the software requirements specification
- Test includes unit testing, integration testing, system testing, and acceptance testing
- The test documents include test plans, cases, scenarios, execution reports, and traceability matrix
Deployment
- The software is delivered to the customer after testing
- A deployment plan which allows for user install; manually, or automated
- This is supported with both a user and installation guide
Maintenance
- Ongoing support and support for enhancements
- This is provided with an operations and maintenance manual
