Software Engineering notes UNIT VI

 

1. Comprehensive Examples using Available Software Platforms / CASE Tools

---

 What are CASE Tools?

CASE stands for Computer-Aided Software Engineering.
These tools help automate different stages of software development like:

• Planning

• Analysis

• Design

• Coding

• Testing

• Maintenance

They increase productivity, maintain consistency, and reduce manual effort.

---

type	Purpose	Example Tools
Upper CASE	Support early SDLC phases (planning, design)	StarUML, Lucidchart, IBM Rational Rose
Lower CASE	Support later SDLC phases (coding, testing, maintenance)	Visual Studio, JUnit, Selenium
Integrated CASE (I-CASE)	Cover full SDLC cycle	Enterprise Architect, Visual Paradigm

---

Example : Using Visual Studio for Development

• Full-featured IDE supporting multiple languages (C#, Python, etc.).

• Integrated debugging, code suggestions, testing support.

• Used in real-world enterprise software development. 

2. Configuration Management in Software Engineering

---

 What is Configuration Management?

Software Configuration Management (SCM) is the process of systematically handling changes in software so that integrity and traceability are maintained throughout the software lifecycle.

In simple words, SCM ensures that:

• The right version of the software is delivered.

• Every change is tracked and documented.

• Developers don’t overwrite each other’s work.

• Code is always stable and secure.

---

 Key Activities in Configuration Management:

---

1. Version Control

• Maintains different versions of software code.

• Tracks who made what changes and when.

• Allows rollbacks to previous versions if a problem occurs.

Tool Example: Git, SVN

---

2. Change Management

• Process of handling requests for changes (bugs, features, improvements).

• Each change is reviewed, approved, tested, and then implemented.

Tool Example: Jira, Trello

---

3. Build Management

• Ensures that the software can be compiled and built reliably from source code.

• Automates building processes.

Tool Example: Maven, Gradle

---

4. Release Management

• Prepares software for deployment to end users.

• Packages the software with proper versioning and release notes.

Tool Example: Jenkins (CI/CD), GitHub Actions

---

5. Configuration Identification

• Defining which components (code, docs, libraries) are part of which version.

---

Benifits	Explanation
Stability	Keeps system working correctly after changes
Collaboration	Multiple developers can work without conflict
Traceability	Who changed what and why
Risk Reduction	Easily revert faulty changes

---

Real-Life Analogy:

Think of SCM like managing a Google Doc with tracked changes — you know who did what, when, and you can restore earlier versions any time!

---

Tools	Example
Version Control	Git, GitHub, Bitbucket
Issue Tracking	Jira, Redmine, Bugzilla
Build Automation	Jenkins, Maven, Gradle
CI/CD Pipelines	GitLab CI, Azure DevOps, CircleCI
