Configuration management and version control in Software Engineering - Step-by-Step Execution

Concept Flow - Configuration management and version control

Start: Code or Config Change

↓

Save Change Locally

↓

Commit Change to Version Control

↓

Push Commit to Shared Repository

↓

Others Pull Latest Changes

↓

Merge Conflicts?

Yes→Resolve Conflicts

↓

Commit Resolved Changes

↓

Track History & Versions

↓

Deploy or Build from Version

End

This flow shows how changes are saved, committed, shared, merged, and tracked in version control to manage software configurations.

Execution Sample

Software Engineering

1. Make code change
2. git add file
3. git commit -m "message"
4. git push origin main
5. Others git pull
6. Resolve conflicts if any

This sequence shows the basic steps of saving, committing, pushing, pulling, and merging code changes using version control.

Analysis Table

Step	Action	Result	Notes
1	Make code change	Local file modified	Change is only on local machine
2	git add file	File staged for commit	Prepares file to be committed
3	git commit -m "message"	Change saved in local repo	Creates a snapshot with message
4	git push origin main	Change sent to remote repo	Others can now access this change
5	Others git pull	Get latest changes	Update local repo with remote changes
6	Merge conflicts?	Check if changes clash	If yes, must resolve before continuing
7	Resolve conflicts	Conflicts fixed locally	Manual fix of overlapping changes
8	git commit resolved changes	Save conflict resolution	Finalizes merge
9	Track history	All changes recorded	Can view or revert any version
10	Deploy or build	Use specific version	Ensures stable software release
11	End	Process complete	Configuration managed and versioned

💡 Process ends after changes are committed, pushed, merged, and deployed successfully.

State Tracker

Variable	Start	After Step 3	After Step 4	After Step 5	After Step 7	Final
Local Code	Original version	Modified and committed	Committed version	Updated with remote	Conflicts resolved	Final merged version
Remote Repo	Old version	Old version	Updated with push	Updated with push	Updated with push	Updated with push
Working Copy Others	Old version	Old version	Old version	Updated with pull	Updated with pull	Updated with pull

Key Insights - 3 Insights

Why do we need to commit changes before pushing?

Committing saves a snapshot locally with a message. Pushing sends these snapshots to the shared repository. Without commit, there is nothing to push. See execution_table step 3 and 4.

What happens if two people change the same file differently?

A merge conflict occurs when pulling changes. It must be resolved manually before committing the merged result. See execution_table steps 6 and 7.

How does version control help in deployment?

It tracks all changes and versions, so you can deploy a stable, tested version anytime. See execution_table step 10.

Visual Quiz - 3 Questions

Look at the execution_table, what is the result immediately after step 3?

A Change saved in local repo

B Change sent to remote repo

C File staged for commit

D Local file modified

💡 Hint

Check the 'Result' column for step 3 in the execution_table.

At which step do others get the latest changes from the remote repository?

A Step 4

B Step 6

C Step 5

D Step 7

💡 Hint

Look for 'Others git pull' action in the execution_table.

If a merge conflict occurs, what must happen next according to the execution flow?

A Make new code changes

B Resolve conflicts manually

C Push changes immediately

D Delete local repository

💡 Hint

See execution_table steps 6 and 7 about merge conflicts.

Concept Snapshot

Configuration management tracks and controls software changes.
Version control saves snapshots (commits) of code.
Changes are committed locally, then pushed to a shared repo.
Others pull updates and merge changes.
Conflicts must be resolved before finalizing.
This ensures history, collaboration, and stable deployments.

Full Transcript

Configuration management and version control help teams manage software changes safely. The process starts with making a code change locally. Then the change is staged and committed, which saves a snapshot with a message. Next, the commit is pushed to a shared remote repository so others can access it. Other team members pull the latest changes to update their local copies. If two people changed the same part differently, a merge conflict occurs and must be resolved manually before committing the merged result. All changes are tracked in history, allowing viewing or reverting versions. Finally, a specific version can be deployed to ensure stable software releases. This flow supports collaboration, prevents loss, and keeps software organized.
