- Feature and Bugfix
- Master and Develop
- Master and Feature
The main branches in Gitflow are "Master" and "Develop." The Master branch represents the stable production version, while the Develop branch is used for ongoing development. Other branches, such as feature and bugfix branches, stem from Develop.
How does Gitflow handle hotfixes compared to GitHub Flow?
- Dedicated Hotfix Branch, Immediate Deployment, Merge to Master and Develop
- Feature Branch for Hotfix, Pull Requests, Automatic Merging
- Forking for Hotfix, Patch Branch, Manual Merging
- No Hotfix Branch, Continuous Deployment, Direct Merge to Master
Gitflow handles hotfixes by creating a dedicated hotfix branch, allowing for immediate deployment, and merging changes both to the master and develop branches, ensuring consistency.
In pessimistic concurrency control, transactions acquire _______ on data items to prevent other transactions from accessing them simultaneously.
- Indexes
- Locks
- Permissions
- Timestamps
In pessimistic concurrency control, transactions acquire locks on data items to prevent other transactions from accessing them simultaneously. This helps maintain data consistency by allowing only one transaction to modify a data item at a time.
In Git, when does a merge conflict typically occur?

Which SDLC model is characterized by multiple cycles of development and testing, with each cycle producing a deliverable product increment?
- Incremental Model
- Iterative Model
- RAD Model
- V-Model
The Incremental Model is characterized by multiple cycles of development and testing, with each cycle producing a deliverable product increment. This iterative approach allows for the incremental release of parts of the system, providing early benefits to stakeholders.
