Study Notes

Agile Method Process

Agile is a software development and project management methodology emphasizing flexibility, collaboration, customer feedback, and iterative progress.
Agile utilizes prototypes to understand client requirements.
Agile incorporates client feedback to make changes to the software.
Agile development uses "sprints" for building software, which are small, actionable blocks of work.

Waterfall Method

Waterfall development is a traditional software development approach.
It follows a sequential and linear process.
Development happens in a step-by-step manner.

Configuring Git

Git is a version control system.
The git config --global user.name "John Doe" command sets your username for Git.
The git config --global user.email [email protected] command sets your email address for Git.
The git status command shows the states of files in your working directory and staging area.
The git commit command takes all staged files and records a new snapshot in the Git database.

Star and Fork

Starring a repository on GitHub marks it as valuable or interesting.
Forking a repository on GitHub creates a copy of the repository under your GitHub account.

VM vs. Container

Virtual Machines are heavy software packages providing complete hardware emulation.
Containers are lightweight and require less system resources than VMs.
Containers are portable, efficient, and enhance application development.
Virtual machines are better for data security and disaster recovery.

Jenkins

Jenkins is an automation server.
Jenkins is used to automate various tasks in the software development lifecycle, from build and testing to deployment and monitoring.
Jenkins supports various types of projects, including Freestyle Projects and Multibranch Pipelines.
Freestyle Projects are flexible and suitable for basic tasks.
Multibranch Pipelines are automatically created and run for each branch in a version control repository.
Artifacts are files produced as a result of a Jenkins job, such as compiled code or deployment packages
SCM integration allows Jenkins to automatically trigger jobs based on changes in the source code repository.
Build triggers are events or conditions that cause a Jenkins job to run.
Plugins extend Jenkins's functionality.

Docker

Docker is a containerization platform.
Docker containers are lightweight and portable, containing all necessary components to run an application, including libraries, dependencies, and an operating system (unlike virtual machines).
Docker containers can be in various states, including:
- Created
- Running
- Paused
- Exited
- Dead
Docker containers can be run in detached mode for background operation or foreground mode for interactive use.

Enterprise Developer Build Tools

Enterprise Developer Build Tools for Windows is a component of Enterprise Developer used for compiling, building, and testing COBOL code.
It provides all of Enterprise Developer's features without needing an IDE.
