Study Notes
Software Engineering Midterm Notes
- Forward Engineering: Aims to move from abstract representation to detailed system implementation, decomposing parts for reuse and optimization.
- Reverse Engineering: Aims to understand an existing system's architecture to create a reusable component or modify performance.
- Scalability Visualization: Important in software evolution to allow detailed breakdown of components within large systems.
- Reengineering: The goal is to improve maintainability through new technology and/or enhancing hardware integration in a large system.
- Abstraction: The reverse of abstraction is decomposition. This means breaking down detailed representations into simpler, higher-level ones.
- Big Bang Engineering: A method of implementing changes to a system all at once rather than incrementally.
- Incremental Engineering: A method of software development where changes are implemented sequentially in small batches to allow for smooth system integration.
- Iterative Engineering: Software development approach wherein the system is developed in incremental steps, each of those steps being reviewed and redeveloped.
- Evolutionary Engineering: This involves gradual changes to a system over time.
- Corrective Maintenance: Improves the system by fixing defects.
- Adaptive Maintenance: Addresses changing environments by making adjustments and changes to the system's code.
- Perfective Maintenance: Aims to enhance user experience and the code's readability.
- Preventive Maintenance: Prevents future errors by improving designs and enhancing code components.
- Software Evolution: Refers to the changes made over time to a software system. Laws include increasing complexity and declining quality.
- Software Rejuvenation: A process that aims to prevent failures due to continuous system operation.
- Evidence-Based Maintenance: An approach to software maintenance that uses empirical research to justify maintenance activities.
- Post-Delivery Maintenance: Activities after the initial software release, including operations like help desks.
- Software Aging: Refers to the issues introduced into a software system due to extended, continuous use.
Software Configuration Management (SCM)
- SCM Version Control: Tracks changes to configuration items to ensure consistency and traceability.
- Sandbox Functionality (SCM): Allows for isolated file editing that doesn't impact the main repository.
- Branch (SCM): A separate line of development in a software project.
- Baseline (SCM): A fixed, stable point used as reference during the development process.
- Baseline Development (SCM): Establishing configuration traceability, including creating version snapshots.
- Trunk (SCM): The primary, or master development path, in a version control system.
- Configuration Audit: An evaluation of a configuration regarding processes, standards, and user requirements.
- Migration (SCM): Moving a system to a different operating environment or technology.
- Workspace Isolation: Enables developers to work on changes without affecting other team members.
- Change Request Workflows (SCM): Systems that document, track, and approve modifications systematically.
- Regression Testing: Aims to ensure that changes don't disrupt existing functionality.
- IEEE/EIA 1219 Process: A standard for managing software maintenance, and contains different stages like delivery, problem identification, and analysis to focus on integration of code changes.
- ISO/IEC 14764 Process: A standard for managing software maintenance activities that focus on ensuring modifications align with organizational goals.
Additional Concepts
- Change Mini-Cycle Model: Incremental changes to a system's code base without extensive investigation, directly impacting the code.
- Full Reuse Model: Reusing existing system components to build a new system.
- Problem and Modification Analysis: A phase in a software maintenance process focusing on identifying changes and impacts.
- Process Implementation: Ensuring a process is implemented, including the needed training, risk analysis, and setting up effective acceptance tests, as part of a software development process.
